HPLC has a wide range of application, for example it is used in pharmaceutical companies in the separation of vitamin C, and it also applied in the legal profession by detecting illegal substances such as cocaine in the urine (Ballinger et al., 2011).
HPLC can be said to be a mass transfer process that involves adsorption. A typical HPLC instrument has a detector, sampler and a pump. The sampler is used to collect the sample, then the pump is used to pass sample through a mobile phase, which mostly consist of an adsorbent such as silica gel. In the mobile phase, the sample mixture will separate because they have different adsorption rates. It is this difference in adsorption rates that HPLC principle relies on. Finally, the detector is used to separate the different components (Kebbekus & Mitra, 1998).
HPLC is one of the most preferred technique in the food industries. It is mostly used in the quality control. HPLC is preferred to other techniques, because it is cheap to maintain and it does not need a very qualified personnel to run it (Ballinger et al., 2011).
An example, where HPLC is applied is the sugar cane industries. After sugar cane has been crushed, it is always squeezed to remove the juice. The juice is then treated with chemicals to kill any fungi which is available in it. It is at this stage, where HPLC finds its use. This is because some of the chemicals always remain in the final product. In connection to this, HPLC is always used to determine, if there are any traces of the chemicals in the final sugar. If there are any, it is then taken back for treatment (Scoog &Holler, 1992).
The main limitation of this technique is that it cannot be used for very complex chemical elements. In ...Download file to see next pagesRead More

Real World Applications of Graphs and Probabilities
...Real World Applications of Graphs and Probabilities Parabolas and Hyperbolas Although both parabola and hyperbola belong to a general of conic shapes and after series of transformations equations of parabola and hyperbola can be rewritten in the same general form, their graphs are different. Parabola looks somewhat similar to one of the two branches of hyperbola; however, there is an important difference between them - symmetry. A parabola is symmetrical with regard to symmetry axis that goes through its vertex; a branch of a hyperbola is not necessarily symmetrical. Graph of a parabola Graph of a...

Techniques used in landscape interpretations
...it is essential for us to understand and appreciate the modern methods of landscape interpretations which are discussed in this paper along. These interpretative techniques have been mentioned by architects, artists and scientists who have utilized these methods to study landscapes around the world. Examining a Landscape Normally, the first step in examining any given landscape is to actually look at the landscape with the naked eye. Of course this may not be possible in certain situations like interpreting the landscapes of other planets or subterranean structures but in most topographical analysis situations it is certainly a clear possibility. Dennis (2003) gives a very interesting...

...extremely lethal to the ozone. Destruction of the ozone leads to increased amounts of UV rays reaching the ground. These UV rays increase the occurrence of cancers such as melanoma and carcinomas. f) Fate of the chemical The danger posed by dichlorodifluoromethane and other CFCs to the ozone led to the formation of the Montreal Protocol in 1987. The adoption of this treaty by countries the world over led to the reduction and eventual ceasing of production and use of CFCs11. Based on the treaty, the ozone layer will be fully restored by 2050. Dichlorodifluoromethane, along with other CFCs is being used to trace the movement and mixing of ocean masses....

Real World Experience #2
...Real World Example Usually we study hypothetical examples, problems and their solution in our contents, thinking that these may not be happen in the real lives and businesses. Actually this thinking is not totally wrong because there are certain theories and models which are not applicable in the real world but still some other problems may arise. Thus the management has to handle all these problems in a way to maintain their operations and the output also. Problem solving is not an easy job. The individual who takes this responsibility of this decision making and the problem solving should take care of each and every aspect of the...

Identification of a compound by mass relationship Lab
...with hydrochloric acid and then identification of the compound based on the Q-value. Q- theoretical value is based on a stoichiometry calculation similar to those done in class while the experimental value of Q is gotten from experiment. Both unknowns end up as a chloride salt at the end of the experiment. Depending on the unknown present, there are two possible chemical reactions that will be performed in the lab: If the unknown is NaHCO3, then the overall reaction in the experiment is: NaHCO3(s) + HCl (aq) NaCl (aq) + CO2 (g) + H2O (l) If the unknown is KHCO3, then the overall reaction in the experiment is: KHCO3(s) + HCl (aq) KCl (aq) + CO2 (g) + H2O (l)...
