Gas Chromatography-Mass Spectroscopy
cires1.colorado.eduGas Chromatography-Mass Spectroscopy Introduction Gas chromatography-mass spectroscopy (GC-MS) is one of the so-called hyphenated analytical techniques. As the name implies, it is actually two techniques that are combined to form a single method ... In liquid chromatography (LC), the mobile phase is a solvent. In gas chromatography (GC), the

Because gas and supercritical fluid chromatography separates samples in the gas phase, the eluents produced after column separation can be directly swept into the ICP-MS torch. However, liquid chromatography elutes, being in a liquid phase, require nebulization similar to that of standard liquid sample introduction. Torch
