Gas Chromatography (GC) with Flame Ionization Detection ... Gas Chromatography, or GC, is a technique that is used to separate, detect, and quantify small volatile compounds in the gas phase. In GC, liquid samples are vaporized, then carried by an inert gas through a long, thin column. Analytes are separated based on their chemical affinity with a coating on the inside of the column. CHROMATOGRAPHY Thermopedia Gas chromatography includes gas adsorption (gas solid) and gas liquid chromatography. Liquid chromatography is subdivided into liquid liquid, liquid solid and liquid gel chromatography. The former characterizes the phase state of the eluent; the second, that of the eluate. Chromatography is classified by the separation mechanism, that is the nature of interaction between a sorbent (an absorbing substance) and a sorbate (a substance being absorbed) as follows: 6. ·Gas Chromatography uid anchored in the tubing.
