Introduction

* The analysis technique chosen is gas chromatography, I'm going to talk about it and I am elected chromatography studies to identify and quantify known materials do. * The principles of gas chromatography * The functions of gas chromatography * Theories of instruments and techniques etc.

PRINCIPLES

Gas chromatography (GC) was first demonstrated for analysis of liquid in the classic paper by james and martin (1952). It was quickly recognised as a rapid and quantitative method for solving hitherto intractable problems, and within a few years became the most popular instrumental method of analysis.

Gas chromatography is an exact imperative analytical apparatus because it can separate the chemical components in the mixture for later use or quantification. Most of the studied samples of mixtures of chemicals. If quantification method is selective for certain components in the mixture is the separation is not required. However, it is often the event that the detector is not explicit abundant and the first separation can be made. There are various types of chromatography as a function of the sample to be examined.

As in the chromatographic procedure is a mobile phase in this case a gas carrying method component of the mixture on the stationary phase. Stationary phase is a tube as a column of liquid or solid cable filled with a high boiling point. The component mixture leaves the column in the order or the greater part of the first voritility varieties.

Chromatography columns are easy able to achieve 100 times more plates than distillation columns of comparable length, and are capable of generating 10,000 times more plates. This performance, used with stationary phases of different polarities and selective detectors provides a very powerful analytical tool.

Gas chromatography is important for quality control, process control, evaluation of process efficiency, safety, environmental monitoring and

    Chromatography serves mainly as a tool for the examination and separation of mixtures of chemical substances. Chromatography is using a flow of solvent or gas to cause the components of a mixture to migrate differently from a narrow starting point in a specific medium, in the case of this experiment, filter paper. It is used for the purification and isolation of various substances. A chromatographically pure substance is the result of the separation. Because purification of substances is required to determine their properties, chromatography is an indispensable tool in the sciences concerned with chemical substances and their reactions.…

    Gas Chromatography separates organic samples much in the same way as column chromatography. The only differences are that it uses a moving gas phase and a stationary liquid phase, and that the temperature of the gas system can be controlled. In a gas chromatograph the sample is shot in with a syringe and is immediately vaporized in a heated injection chamber. It is then introduced to a moving stream of gas called the carrier gas which sweeps the vaporized sample into a column filled with particles filled with liquid adsorbent. This column is usually filled with liquid that has a low vapor pressure and high boiling and is called the stationary phase. This phase is also usually coated onto a support material very evenly and packed into a tubing apparatus as evenly as possible and placed in the temperature controlled oven. When organic solutions are passed through the tubing van der Waals forces attract the nonpolar molecules especially if they have large molecular weights. Polar molecules can be attracted in many ways. Interactions include salt formation, coordination, hydrogen bonding, and even dipole-dipole. Through these interactions the molecules in the vaporized sample will separate accordingly. Finally at the end where the gases come out is a detector which generates a signal that is recorded on a strip chart recorder.…

    Answer: Gas chromatography (GC) – utilized by scientists in order to be able to separate the volatile particles of a mixture. This is done with the aid of a syringe where the sample is drawn and then transferred to the port of the gas chromatograph called the into injector port. It is then set to reach a very high temperature which exceeds the appropriate boiling point for the substances, thus, allowing the particles to evaporate. Then helium is introduced in order to facilitate the flow the evaporated substances to the gas chromatograph column where the separation will then take place (www.gas-chromatography.net).…

    Chromatograph method is a method of separating mixtures of two or more compounds. Two phases are important in this method; one that is stationary and one that is moving. Chromatography works on the principle that different compounds will have different solubilities and adsorption to the two different phases between which are to be partitioned. Thin Layer Chromatography (TLC) is a solid-liquid technique. The mixture is observed when it is in two different phase; a solid (stationary phase) and a liquid (moving phase). Thin Layer Chromatography (TLC) is a technique which is sensitive, cheap and fast. A thin layer chromatograph plate is used to identify drug component under UV. It is used to support the identity of a compound in a mixture when the Rf of a compound is compared with the Rf of a known compound.…

    This method is very useful because not only is it a relatively quick process, but also requires only small quantities of materials. The substances being tested are first distributed between a stationary phase and a mobile phase. The stationary phase refers to a piece of high quality filter paper used for testing. The mobile phase references the developing solution that travels up the stationary phase, leaving the samples in its traces. The sample then separates according to two main concepts: how strongly the solution absorbs on the stationary phase versus how well they dissolve into the mobile phase.…
