Gas Chromatography
Gas Chromatography is a technique used to separate volatile components in the gas phase. Gas Chromatography is a chromatographic technique that uses an inert gas as the mobile phase. When the stationary phase is solid in Gas Chromatography then it is called Gas-Solid Chromatography while when a liquid on an inert layer is used as a stationary phase then it is called Liquid-Gas Chromatography.
A Gas Chromatographer consists of a sample injection unit, a column, and a detector. The sample to be analyzed is injected into the sample injection system which heats up the sample and vaporizes it. After the sample heats up it moves up along with the gas mobile phase through the column which is separated by the stationary phase and the final compound is analyzed by the detector. The technique of Gas Chromatography was introduced by Mikhail Semenovich Tsvett.
Gas Chromatography is extensively used for the analysis of volatile mixtures, in analyzing air samples to analyze air quality, in the pharmaceutical industry, and in analyzing environmental toxins.
Chromatography
Chromatography is the separation of mixtures by distribution between two or more immiscible phases. In chemical laboratories, where it is used for analysis, isolation, and purification, chromatography is the most used separation technique. It is also frequently used in the chemical process industry as a part of small and large-scale production.
There are many types of Chromatography, e.g. Adsorption Chromatography, Thin Layer Chromatography, Column Chromatography, Partition Chromatography, etc. Paper Chromatography is an example of Partition Chromatography.
