Gas Chromatography - What It Is and How It Works

Gas Chromatography - What It Is and How It Works Gas chromatography (GC) is an analytical technique used to separate and analyze samples that can be vaporized without thermal decomposition. Sometimes gas chromatography is known as gas-liquid partition chromatography (GLPC) or vapor-phase chromatography (VPC). Technically, GPLC is the most correct term, since the separation of components in this type of chromatography relies on differences in behavior between a flowing mobile gas phase and a stationary liquid phase. The instrument that performs gas chromatography is called a gas chromatograph. The resulting graph that shows the data is called a gas chromatogram. Uses of Gas Chromatography GC is used as one test to help identify components of a liquid mixture and determine their relative concentration. It may also be used to separate and purify components of a mixture. Additionally, gas chromatography can be used to determine vapor pressure, heat of solution, and activity coefficients. Industries often use it to monitor processes to test for contamination or ensure a process is going as planned. Chromatography can test blood alcohol, drug purity, food purity, and essential oil quality. GC may be used on either organic or inorganic analytes, but the sample must be volatile. Ideally, the components of a sample should have different boiling points. How Gas Chromatography Works First, a liquid sample is prepared. The sample is mixed with a solvent and is injected into the gas chromatograph. Typically the sample size is small in the microliters range. Although the sample starts out as a liquid, it is vaporized into the gas phase. An inert carrier gas is also flowing through the chromatograph. This gas shouldnt react with any components of the mixture. Common carrier gases include argon, helium, and sometimes hydrogen. The sample and carrier gas are heated and enter a long tube, which is typically coiled to keep the size of the chromatograph manageable. The tube may be open (called tubular or capillary) or filled with a divided inert support material (a packed column). The tube is long to allow for a better separation of components. At the end of the tube is the detector, which records the amount of sample hitting it. In some cases, the sample may be recovered at the end of the column, too. The signals from the detector are used to produce a graph, the chrom atogram, which shows the amount of sample reaching the detector on the y-axis and generally how quickly it reached the detector on the x-axis (depending on what exactly the detector detects). The chromatogram shows a series of peaks. The size of the peaks is directly proportional to the amount of each component, although it cant be used to quantify the number of molecules in a sample. Usually, the first peak is from the inert carrier gas and the next peak is the solvent used to make the sample. Subsequent peaks represent compounds in a mixture. In order to identify the peaks on a gas chromatogram, the graph needs to be compared a chromatogram from a standard (known) mixture, to see where the peaks occur. At this point, you may be wondering why the components of the mixture separate while they are pushed along the tube. The inside of the tube is coated with a thin layer of liquid (the stationary phase). Gas or vapor in the interior of the tube (the vapor phase) moves along more quickly than molecules that interact with the liquid phase. Compounds that interact better with the gas phase tend to have lower boiling points (are volatile) and low molecular weights, while compounds that prefer the stationary phase tend to have higher boiling points or are heavier. Other factors that affect the rate at which a compound progresses down the column (called the elution time) include polarity and the temperature of the column. Because temperature is so important, it is usually controlled within tenths of a degree and is selected based on the boiling point of the mixture. Detectors Used for Gas Chromatography There are many different types of detectors that can be used to produce a chromatogram. In general, they may be categorized as non-selective, which means they respond to all compounds except the carrier gas, selective, which respond to a range of compounds with common properties, and specific, which respond only to a certain compound. Different detectors use particular support gases and have different degrees of sensitivity. Some common types of detectors include: Detector Support Gas Selectivity Detection Level Flame ionization (FID) hydrogen and air most organics 100 pg Thermal conductivity (TCD) reference universal 1 ng Electron capture (ECD) make up nitriles, nitrites, halides, organometallics, peroxides, anhydrides 50 fg Photo-ionization (PID) make up aromatics, aliphatics, esters, aldehydes, ketones, amines, heterocyclics, some organometallics 2 pg When the support gas is called make up gas, it means gas is used to minimize band broadening. For FID, for example, nitrogen gas (N2) is often used. The users manual that accompanies a gas chromatograph outlines the gases that can be used in it and other details.

Biography of Bernardo OHiggins, Liberator of Chile

Biography of Bernardo O'Higgins, Liberator of Chile Bernardo OHiggins (August 20, 1778–October 24, 1842) was a Chilean landowner, general, president, and one of the leaders of its struggle for independence. Although he had no formal military training, OHiggins took charge of the ragged rebel army and fought the Spanish from 1810 to 1818, when Chile achieved its independence. Today, he is revered as the liberator of Chile and the father of the nation. Fast Facts: Bernardo O'Higgins Known For:  Leader during Chiles struggle for independence, general, presidentBorn:  August 20, 1778 in Chilln, ChileParents: Ambrosio OHiggins and Isabel RiquelmeDied:  October 24, 1842 in Lima, PeruEducation: San Carlos College, Peru, Catholic school in EnglandNotable Quote: Lads! Live with honor, or die with glory! He who is brave, follow me! Early Life Bernardo was the illegitimate child of Ambrosio OHiggins, a Spanish officer born in Ireland who immigrated to South America and rose through the ranks of the Spanish bureaucracy, eventually reaching the high post of Viceroy of Peru. His mother Isabel Riquelme was the daughter of a prominent local, and he was raised with her family. Bernardo only met his father once (and at that time he did not know who he was) and spent most of his early life with his mother and traveling. As a young man, he went to England, where he lived on a small allowance that his father sent him. While there, Bernardo was tutored by legendary Venezuelan Revolutionary Francisco de Miranda. Return to Chile Ambrosio formally recognized his son in 1801 on his deathbed, and Bernardo suddenly found himself the owner of a prosperous estate in Chile. He returned to Chile and took possession of his inheritance, and for a few years he lived quietly in obscurity. He was appointed to the governing body as the representative of his region. Bernardo might well have lived his life as a farmer and local politician if it were not for the great tide of independence that was building in South America. OHiggins and Independence OHiggins was an important supporter of the September 18 movement in Chile, which began the nations struggle for independence. When it became apparent that the actions of Chile would lead to war, he raised two cavalry regiments and an infantry militia, mostly recruited from families who worked his lands. As he had no training, he learned how to use weapons from veteran soldiers. Juan Martà ­nez de Rozas was president and OHiggins supported him, but Rozas was accused of corruption and criticized for sending valuable troops and resources to Argentina to help the independence movement there. In July 1811, Rozas stepped down and was replaced by a moderate junta. OHiggins and Carrera The junta was soon overthrown by Josà © Miguel Carrera, a charismatic young Chilean aristocrat who had distinguished himself in the Spanish army in Europe before deciding to join the rebel cause. OHiggins and Carrera would have a tempestuous, complicated relationship for the duration of the struggle. Carrera was more dashing, outspoken, and charismatic, while OHiggins was more circumspect, brave, and pragmatic. During the early years of the struggle, OHiggins was generally subordinate to Carrera  and dutifully followed his orders as best he could. This power dynamic would not last, however. The Siege of Chilln After a series of skirmishes and small battles against the Spanish and royalist forces from 1811–1813, OHiggins, Carrera, and other rebel generals chased the royalist army into the city of Chilln. They laid siege to the city in July of 1813, in the middle of the harsh Chilean winter. The siege was a disaster for the rebels. The patriots could not completely dislodge the royalists. When they did manage to take part of the town, the rebel forces engaged in raping and looting, which caused the province to sympathize with the royalist side. Many of Carreras soldiers, suffering in the cold without food, deserted. Carrera was forced to lift the siege on August 10, admitting that he could not take the city. Meanwhile, OHiggins had distinguished himself as a cavalry commander. Appointed Commander Not long after Chilln, Carrera, OHiggins, and their men were ambushed at a site called El Roble. Carrera fled the battlefield, but OHiggins remained despite a bullet wound in his leg. OHiggins turned the tide of the battle and emerged a national hero. The ruling junta in Santiago had seen enough of Carrera after his fiasco at Chilln and his cowardice at El Roble and made OHiggins commander of the army. OHiggins, always modest, argued against the move, saying that a change of high command was a bad idea, but the junta had decided: OHiggins would lead the army. The Battle of Rancagua OHiggins and his generals battled Spanish and royalist forces throughout Chile for another year before the next decisive engagement. In September 1814, Spanish General Mariano Osorio was moving a large force of royalists into position to take Santiago and end the rebellion. The rebels decided to make a stand outside the town of Rancagua, on the way to the capital. The Spanish crossed the river and drove off a rebel force under Luà ­s Carrera (brother of Josà © Miguel). Another Carrera brother, Juan Josà ©, was trapped in the city. OHiggins bravely moved his men into the city to reinforce Juan Josà © in spite of the approaching army, which far outnumbered the rebels in the city. Although OHiggins and the rebels fought very bravely, the result was predictable. The massive royalist force eventually  drove the rebels out of the city. The defeat could have been avoided had Luà ­s Carreras army returned, but it did not- under orders from Josà © Miguel. The devastating loss at Rancagua meant that Santiago would have to be abandoned: There was no way to keep the Spanish army out of the Chilean capital. Exile OHiggins and thousands of other Chilean rebels made the weary trek into Argentina and exile. He was joined by the Carrera brothers, who immediately began jockeying for position in the exile camp. Argentinas independence leader,  Josà © de San Martà ­n, supported OHiggins, and the Carrera brothers were arrested. San Martà ­n began working with Chilean patriots to organize the liberation of Chile. Meanwhile, the victorious Spanish in Chile were punishing the civilian population for their support of the rebellion. Their harsh brutality only caused the people of Chile to long for independence. When OHiggins returned, the general population was ready. Return to Chile San Martà ­n believed that all of the lands to the south would be vulnerable as long as Peru remained a royalist stronghold. Therefore, he raised an army. His plan was to cross the Andes, liberate Chile, and then march on Peru. OHiggins was his choice as the man to lead Chiles liberation. No other Chilean commanded the respect that OHiggins did (with the possible exception of the Carrera brothers, whom San Martà ­n did not trust). On January 12, 1817, a formidable rebel army of some 5,000 soldiers set out from Mendoza to cross the mighty Andes. Like  Simà ³n Bolà ­vars epic 1819 crossing of the Andes, this expedition was very harsh. San Martà ­n and OHiggins lost some men in the crossing, although their sound planning meant that most soldiers survived. A clever ruse had sent the Spanish scrambling to defend the wrong passes and the army arrived in Chile unopposed. The Army of the Andes, as it was called, defeated the royalists at the  Battle of Chacabuco  on February 12, 1817, clearing the path to Santiago. When San Martà ­n defeated the Spanish last-gasp attack at the  Battle of Maipu  on April 5, 1818, the rebel victory was complete. By September 1818, most Spanish and royalist forces had retreated to try to defend Peru, the last Spanish stronghold on the continent. End of the Carreras San Martà ­n turned his attention to Peru, leaving OHiggins in charge of Chile as a virtual dictator. At first, he had no serious opposition: Juan Josà © and Luis Carrera had been captured attempting to infiltrate the rebel army. They were executed in Mendoza. Josà © Miguel, OHiggins greatest enemy, spent the years from 1817 to 1821 in southern Argentina with a small army, raiding towns in the name of gathering funds and weapons for liberation. He was finally executed after being captured, ending the long-standing and bitter OHiggins-Carrera feud. OHiggins the Dictator OHiggins, left in power by San Martà ­n, proved to be an authoritarian ruler. He hand-picked a Senate and the 1822 Constitution allowed representatives to be elected to a toothless legislative body.  OHiggins was a de facto dictator. He believed that Chile needed a strong leader to implement change and control simmering royalist sentiment. OHiggins was a liberal who promoted education and equality and curtailed the privileges of the wealthy. He abolished all noble titles, even though there were few in Chile. He changed the tax code and did much to encourage commerce, including the completion of the Maipo Canal. Leading citizens who had repeatedly supported the royalist cause saw their lands taken away if they had left Chile and they were heavily taxed if they remained. The Bishop of Santiago, the royalist-leaning Santiago Rodrà ­guez Zorrilla, was exiled to Mendoza. OHiggins further alienated the church by allowing Protestantism into the new nation and by reserving the right to meddle in church appointments. He made many improvements to the military, establishing different branches of service, including a Navy to be led by the Scotsman Lord Thomas Cochrane. Under OHiggins, Chile remained active in the liberation of South America, often sending reinforcements and supplies to San Martà ­n and  Simon Bolà ­var, then fighting in Peru. Downfall OHiggins support began to erode quickly. He had angered the elite by taking away their noble titles and, in some cases, their lands. He then alienated the commercial class by continuing to contribute to expensive wars in Peru. His finance minister Josà © Antonio Rodrà ­guez Aldea was revealed to be corrupt, using the office for personal gain. By 1822, hostility to OHiggins had reached a crucial point. The opposition to OHiggins gravitated towards General Ramà ³n  Freile as a leader, himself a hero of the Independence wars, if not a hero of OHiggins stature. OHiggins attempted to placate his foes with a new constitution, but it was too little, too late. Seeing that cities were prepared to rise against him in arms, OHiggins agreed to step down on January 28, 1823. He remembered only too well the costly feuding between himself and the Carreras and how a lack of unity had almost cost Chile its independence. He went out in dramatic fashion, baring his chest to the assembled politicians and leaders who had turned against him and inviting them to take their bloody revenge. Instead, all present cheered for him and escorted him to his home. Exile General Josà © Marà ­a de la Cruz claimed that OHiggins peaceful departure from power avoided a good deal of bloodshed and said, OHiggins was greater in those hours than he had been in the most glorious days of his life. Intending to go into exile in Ireland, OHiggins made a stop in Peru, where he was warmly welcomed and given a large estate. OHiggins had always been a somewhat simple man and a reluctant general, hero, and president, and he happily settled into his life as a landowner. He met Bolà ­var and offered his services, but when he was offered only a ceremonial position, he returned home. Final Years and Death During his final years, OHiggins acted as an unofficial ambassador from Chile to Peru, although he never did return to Chile. He meddled in the politics of both countries, and he was on the verge of being unwelcome in Peru when he was invited back to Chile in 1842. He did not make it home, as he died of heart trouble while en route on October 24, 1842. Legacy Bernardo OHiggins was an unlikely hero. He was a bastard for most of his early life, unrecognized by his father, who was a devout supporter of the king. Bernardo was ingenious and dignified, not particularly ambitious nor an especially dazzling general or strategist. He was in many ways as unlike Simà ³n Bolivar as it is possible to be: Bolà ­var had much more in common with the dashing, confident Josà © Miguel Carrera. Nevertheless, OHiggins had many positive qualities that were not always apparent. He was brave, honest, forgiving, and dedicated to the cause of liberty. He did not back down from fights, even those he could not win. During the wars of liberation, he was often open to compromise when more stubborn leaders like Carrera were not. This prevented unnecessary bloodshed among rebel forces, even if it did mean repeatedly allowing the hot-headed Carrera back into power. Like many heroes, most of OHiggins failings have been forgotten and his successes are exaggerated and celebrated in Chile. He is revered as the Liberator of his country. His remains lie in a monument called The Altar of the Fatherland. A city is named after him, as well as several Chilean navy ships, countless streets, and a military base. Even his time as dictator of Chile, for which he has been criticized for clinging too tightly to power, is viewed by many historians as more beneficial than not. He was a strong personality when his nation needed guidance, yet by most accounts, he did not overly repress the people or use his power for personal gain. Many of his liberal policies, seen as radical at the time, are respected today.

Global Positioning for Financial Services Essay Example | Topics and Well Written Essays - 250 words

Global Positioning for Financial Services - Essay Example In investment banking, investors were taxed on investment income but retail banking customers were taxed on savings (BROWN, 2007). The circular flow of income describes the reciprocal circulation of income between producers and consumers. The interdependent entities are producers, referred to as firms, and consumers referred to as households. These entities provide each other with factors, thus facilitating the flow of income. The firms produce and supply to consumers. The consumers intend to use the goods to meet their wants (RANDALL & MILLWOOD, 1983).Consumers’ expenditure is the income on the firms’ side. On the other hand, households provide the firms with factors of production and in return, they receive the reward which is income on their part. The structure for financial services regulation in the United Kingdom changed tremendously 1st April 2013. The then banking regulator, the Financial Services Authority was abolished and replaced with two institutions. First, the Financial Conduct Authority; mandated with watching the behavioral conduct, mainly regulating conduct related to the marketing of financial products. Secondly, the Prudential Regulation Authority; its mandate is to ensure the stability of financial services. The Bank of England was empowered to have direct supervision on the entire banking system through one of its part, Financial Policy committee (JOHNSON, 2000).

Comparative democratisation Essay Example | Topics and Well Written Essays - 2000 words

Comparative democratisation - Essay Example The death of Franco elevated Dan Juan Carlos de Bourbon to the monarchy. Until Franco's death, Juan Carlos had discreetly stood in the background and served to follow the dictator's plan. However once in power as king of Spain Juan Carlos facilitated the development of the current political system, as his father, Don Juan de Bourbon had advocated since 1946. Juan Carlos began his reign without leaving the confines of Franco's legal system. As such he swore fidelity to the principles of the movement national, the sole legal party of the Franco era. He took possession of the crown before the Francoist Cortes Generales and respected Ley Organica del Estado (the organic law of the state) for the appointment of his first head of government. He showed the beginning of transition through his speech before the Cortes. The first government of Juan Carlos was presided over by Carlos Arias Navarro. The king made this appointment in accordance with the guidelines of the 1966 Ley organica Del Estado (organic law of the state). However in July 1976, as Prime Minister Arias Navarro continued to delay reform and object to democratisation, King Juan Carlos demanded his resignation. Fernandez Miranda, as president of the council of the kingdom, obtained Adolfo Suarez's placements on the new list of three candidates for head of the government. The king chose Suarez because he felt he would be able to meet the challenge of the would be political process that lay ahead. Adolfo Suarez quickly presented a clear program based on how two points; (a) The development of a law for political reform that once approved by the Cortes and Spanish public in a referendum would open the constituent process for creating a liberal democracy in Spain. (b) A call for democratic elections in June 1977, in order to elect a Cortes that would be charged with drawing up a new democratic constitution. Despite all difficulties from the army and opposition Suarez's project went underway without delay between July 1976 and June 1977. The draft of the law for political reform (Ley para la Reforma politiza) written by Torcuato Fernandez Miranda was approved by the Suarez Government in September 1976. This law was debated throughout the month of November by Cortes under the presidency of Fernandez-Miranda. It was approved with 425 votes in favour, 598 against and 13 abstentions. The Suarez government wanted to gain further legitimacy for the changes through a popular referendum with 77.72 % participation rate. 94% of the voters voted in favour of the changes to add to his credibility Suarez, freed 400 prisoners in July 1976. He also granted blanket amnesty in May same year. In December 1976, he disbanded the Tribunal de Order Publica (TOP), a sort of Francoist secret police. He legalized the right to strike, with the right to unionize being granted a month after Suarez initiated political contact with the opposition by meeting Felipe Gonzalez, secretary general of the PSOE in 1976. However the big problem was for po litical normalization was the legalization of the communist party of Spain (Partido communista de Espania). PCE's secretary general, Santiago Carrillo's offer of a "social pact" pushed Suarez to take the riskiest step of transition by legalizing PCE in April 1977. To resolve the difficulty of a group of hard -liner Francoist led by Jose Antonio Giron, Suarez centered on General Diez Alegria. He decided to give the members this group the

Descriptive Essay - The Evangelic Church :: Descriptive Essay, Descriptive Writing

It may seem a little bit strange, but my favorite place in town in none other than this beautiful Evangelic Church. However, it wasn’t always so. When I was a child I used to be frightened of entering such a place for it seemed so imposing and somewhat dangerous, especially when music was being played. One day, in order to keep a promise I had made, I saw myself forced to enter. It took me quite a while to get the courage to pass through the old oak door, but the moment I stepped in, I realized just how enchanting and breathtaking this building could be. Its fantastic architecture and exquisite frescoes reflect perfectly the unity between this earth and the unseen kingdom of angels in such a manner that one cannot say where one ends and the other begins. The way in which the church was built is also the vivid testimony of a medieval period. Although it is a place that can sometimes be cold and ask for respect it is where prayers are answered and magic is done. An overwhelming feeling of inner harmony takes over you once you enter and God seems much closer. Darkness and light are welded perfectly together creating Redemptionâ⠂¬â„¢s house. The tower allows you to see the entire town from the smallest river to the biggest building site, offering you its mightiness. In the early summer mornings, when the sunshine is young and playful, inside the church another realm is born. Sitting in the back rows one can see a heavenly mist flowing though the windows and filling the sleepy altar with life and hope. It is a different dimension in the breast of an unsuspecting world. Moments such as these bring you joy and reassurance and also show you that there really is someone out there: your soul is elevated, your mind is thirsty for new experiences and your body is strengthened. Each time I come to the Evangelic Church something changes inside myself for the better.

No matter whether one chooses to stay at home with one’s children or work outside the home, there are definite trade-offs to consider. Mothers who leave home each day and head to work have the possibility of conversations with adults throughout the day beside their husbands. This gives them a higher degree of intellectual stimulation. They also tend to dress a little better, putting on a professional outfit instead of donning workout clothes or jeans to face the day with their kids. Knowing that they have a busy work schedule also means that they treasure the time with their kids more, and they also have more money to help them enjoy that time. On the other hand, being a working mother means constant fatigue. People who face a long commute with small children waiting on both sides of it feel like they never get enough sleep. Working also means missing out on some memories, such as playdates, first words or steps and even school assemblies. Also, dealing with colleagues who do not understand how hard all the juggling is also a frustration. Advantages Gone are the days when mother devoted her full life for development of her children. Today, women are becoming more active, independent and prefer progress in their career rather than been recognized as just housemakers. Career oriented women continue their work soon after completion of their maternity leave. Many working women start the job early due to financial needs of their family. There can be different reasons for women to go to work instead of staying at home. Sometimes it is very difficult for women to go for work after delivery. In the initial period she may feel insecure for her child.she needs to join work soon after few months of child birth. If she has someone in her family like in-laws or grand parents to look after her child, then she may feel secured for her child. Some working women need to sacrifice career if they don’t have any option for taking care of their child. Many women prefer to leave their career whiles some women prefer to work from home. Some women choose to continue their job, in such case theymake some arrangement to look after their children. Women with financial problem also continue their job due to needs of family. There are many advantages and disadvantages of working mother for their children. Advantage for Children of Working Mother Children of working mother start doing their own work themselves from childhood as compared to children of non-working mother. Children of non-working mother depend on their mother evens for small needs. For example, if a child of non-working woman needs any toy to play, he asks his mother to give him that toy. They become fully dependant on their mother as she is easily available to them for the whole day. Children of working mother have no option and thus, they learn to do many things themselves. They become more independent and responsible in their work. Many husbands help their working spouse in household work. So when the children observe their father doing work at home and helping their mother, thus they also learn to help their parents. In this way, they can learn self awareness and discipline from early age. In addition, the children become co-operative from childhood. It is not possible for non working woman because she is expected to keep everything ready for her husband and children. Therefore, children of non-working mother become more lazier and dependant on parents as compared to children of working mother. Highly educated, working parents can give better education to their children. They know to provide all necessary facilities for the ideal development of their children omitting the unnecessary ones. They also motivate their children to participate in different activities as they can afford such expenses due to higher family income. On the other side it might not possible to afford such expense for many parents, if only father is working in family. Working mother might find more affection towards her children when she comes back from her work as she missed her children for whole the day. She might feel find more attached to  her kids and vice versa. Thus, mother and children become more attached to one other. Non-working mother stays with her children for whole the day, therefore she doesn’t find such feeling of missing her kids and children also takes her for granted. Children of working mothers become practical and more intellectual. They can take wise decision themselves and become independent, confident and more active in their work. Disadvantage for Children of Working Mother Some working mothers have to take their child to childcare center as there is no one in her family tocare for child. In such case she needs to compromise in development of her kids and feels guilty for not sparing good time to raise her kids. If a child doesn’t have any siblings, sometimes he feels lonely as he has no one to express his feelings or thoughts or finds nobody to play with them. Some Working parents cannot spare good time with their children and don’t have time to listen to problems of their children. Therefore, children get frustrated or depressed as they don’t have anyone to share their feelings. Working mother needs to handle home and office work together. Therefore, she may get tired at the end of the day. In such case she may not be able to understand her children’s problem and may get angry with their children if they don’t listen or obey her instructions. Working mother may not be able to attend children’s school program due to hectic schedule at work or leave problems.

Essay about Shakespeare’s Characterisation of Caliban

Caliban is arguably one of the most complex characters in Shakespeare’s The Tempest, despite his low position in the social hierarchy. Primarily, we form our first impression of Caliban through what Prospero says about him. Prospero draws parallels between Caliban and his other servant Ariel, who was ‘too delicate’ to perform the ‘abhorred’ commands of the witch Sycorax. He then goes on to compare Ariel with Caliban; â€Å"a freckled whelp hag born – not honoured with/A human shape.† In line 317 of the play, Prospero refers to Caliban as a ‘tortoise’ and then immediately compares him to Ariel, who is a ‘fine apparition.’ This shows the variation of the two servants and shows Prospero’s obvious derogatory attitude towards Caliban and his biased†¦show more content†¦Prospero calls to Caliban who is on the other side of his cave, who replies â€Å"there’s wood enough within.† Caliban a ssumes that Prospero is calling to give him work of some sort. This unwillingness to work implies how lazy Caliban is, and despite his position as a slave, refuses to obey his master’s commands.

He says: â€Å"As wicked dew as e’er my mother brushed With raven’s feather from unwholesome fen Drop on you both! A south-west wind blow on ye And blister who all o’er†. This first impression from Caliban himself is not a good one. With the aforementioned quotation, he immediately backs up any negative things that Prospero has said about him, and furthermore establishes a negative connection with the audience. We are then informed of how Caliban once tried to rape Miranda. When Prospero raises this point, Caliban responds in an unashamed manner, saying: â€Å"O ho! O ho! Would’t had been done! Thou didst prevent me. I had peopled else The isle with Calibans!† Certain questions have been raised regarding the mentality of Caliban, in the sense that he could be categorised as both a human being and a wild animal. There is evidence to suggest that Caliban is human because he has the qualities and emotions of a human being, as well as a varied and complex vocabulary.
