Used Gas Chromatography GC for sale with warranties and worldwide shipping Gas Chromatography is also sometimes referred to as GLC or Gas-Liquid Chromatography. Gas chromatography happens in a capillary or packed column. During the mobile separation phase the substance is a gas, Therefore this technique is referred to as gas chromatography.
