Chromatography Instruments

 

 

Chromatography instruments used to separate chemical mixtures, carried by liquids or gases, into components as a result of differential distribution of the solutes as they flow around or over a stationary liquid or solid phase. High performance liquid chromatography (HPLC) is one mode of chromatography. Chromatography instruments can be defined as separation techniques involving mass-transfer between stationary and mobile phases. Gas chromatography is a technique used to separate volatile organic compounds. Gas chromatography columns (GC columns) are of two types: packed and capillary. Solutes to be measured travel through the column at a rate primarily determined by their gas chromatography detectors (GC detectors), which identify solutes as they exit the chromatographic column. A chromatogram is generated plotting the signal versus time, physical properties, and the temperature and composition of the column.
