Gc ms stationary phase
WebAnd one of the reasons is that in chromatography, it's always an interaction between the two phases. Here it's the vapor phase, or the gas phase, with the liquid phase, also known as the stationary phase. So compounds like this orange one that move really fast, really, really like to interact with the gas. And this is because they probably have ... WebFeb 12, 2024 · The most typical stationary phase used in GC-MS analysis is a liquid phase contained in a short (10–30 m length) and narrow (0.1-0.25 mm internal diameter) column.. The neutral molecules are separated and then elute through a heated transfer line into the mass spectrometer, which is not necessary for GC-MS analysis unless the analytes are ...
