Mumbai, India (PressExposure) November 30, 2009 -- What is Chromatography?
It is a broad range of laboratory techniques used to separate and or to analyze complex mixtures. Chromatography may be preparative or analytical. Preparative chromatography seeks to separate the components of a mixture and Analytical chromatography normally for measure the relative proportions of analytics in a mixture.
Types of Chromatography
A chromatograph is equipment that enables a sophisticated separation e.g. gas chromatographic or liquid chromatographic separation.
Gas chromatography Gas chromatography (GC), also sometimes known as Gas-Liquid chromatography, (GLC), is a separation technique in which the mobile phase is a gas. Gas Chromatography (GC) is used to separate volatile components of a mixture. Gas chromatography is always carried out in a column, which is typically "Packed" or "Capillary"
Liquid chromatography Liquid chromatography (LC) is a separation technique in which the mobile phase is a liquid. Liquid chromatography can be carried out either in a column or a plane. Present day liquid chromatography that generally utilizes very small packing particles and a relatively high pressure is referred to as high performance liquid chromatography (HPLC).
