Advances in gas chromatography
Gas chromatography is a generally a word used to give information about the group of analytical separation techniques used to analyse volatile materials in the gas phase. In this chromatography, the components of a sample are dissolved in a solvent and vaporized which results in the separation of analyte by differentiating the sample between two phases. Gas chromatography is one of the important types of chromatography that does not use the mobile phase for reacting with the analyte. If the stationary phase consists of solid adsorbent, termed gas-solid Chromatography or a liquid on an inert support, termed gas-liquid chromatography (GLC). Gas Chromatography Mass Spectrometry (GC-MS) is the advanced technique of Gas Chromatography. Gas chromatography can be used in many different fields such as pharmaceutical industry, cosmetology and even environmental toxins.
