Info

Gas Chromatography • Similar to HPLC except the moving phase is a gas • Nitrogen, helium • Low flow resistance of gas • High flow rates • Less time • Temperature gradient allows multiple xenobiotics to be analyzed at once • Partitioning depends on natural volatility • Temp < 572° F (300° C )
Gas Chromatography • Expensive • Screening or confirmatory • High specificity <strong>and</strong> sensitivity • Quantitation <strong>and</strong> broad screening • Temperature gradient • Analyte volatilized in injector, column kept hot • Heat labile cannot be assessed
