In Gas Chromatography, a sample is vaporized and carried by an inert gas (often helium or nitrogen) through a column packed with a stationary phase. The separation occurs based on the interaction of the sample components with the stationary phase and their boiling points. Detectors such as Flame Ionization Detectors (FID) or Mass Spectrometers (MS) provide qualitative and quantitative information about the separated components.
GC is particularly useful in catalysis for analyzing reaction kinetics, determining product distribution, and identifying intermediates in gas-phase reactions.
