assets.thermofisher.comcontaminants may be used to keep the gas cell clean. FTIR analysis can be used to monitor the quality of individual gas samples (e.g., pure specialty gases) or to create concentration trend charts from flowing sample streams (e.g., continuous emissions monitoring—CEM). Unlike gas chromatography (GC), FTIR spectroscopy can
An Introduction to Gas Chromatography Mass Spectrometry
www.ucl.ac.ukThe two principal types of chromatography are gas chromatography (GC) and liquid chromatography (LC). Gas chromatography separates gaseous substances based on partitioning in a stationary phase from a gas phase. Liquid chromatography includes techniques such as size exclusion (separation based on molecular size), ion

cdn.intechopen.com2. Gas chromatography In a gas chromatographic system, the sample to be analyzed may be a liquid solution or a collection of molecules adsorbed on a surface, e.g., the solid-phase microextraction (SPME) system. During the transfer into the GC, the sample is volatilized by rapid exposure to a zone
