Gas chromatography (GC) is used for the analytical separation of volatile substances in the gaseous phase. This chromatographic technique is widely used in various fields of research and industrial ...

EVIDENCE has recently been presented which demonstrated the effects of alteration of the chemical composition of the stationary liquid upon the resolution of the methyl esters of long-chain saturated ...

Gas chromatography (GC) is an older analytical technique that is still widely used today. It is a technique that can be used with both inorganic and organic analytes, but the one requirement is that ...

Regulatory changes from the EPA have catalyzed significant innovations in gas chromatography, enhancing analytical ...

THE radiohomogeneity of tritium- and carbon-14-labelled methyl linoleate in vivo and the stability of the labelled methyl esters during gas–liquid chromatography has recently been investigated 1. It ...

Equipment for gas chromatography, liquid chromatography and mass spectrometry is complex, with multiple subsystems that control the flow of sample analyte, carrier gas and solvent fluids. The ...

Analysts interested in quantifying volatile organic compounds like disinfection byproducts in liquid samples should consider using the gas chromatography system. There are two gas chromatography (GC) ...

Analysts interested in quantifying volatile organic compounds or pesticides in liquid samples should consider using the gas chromatography - mass spectroscopy (GC-MS) system. The gas chromatography ...

Thin-layer chromatography (TLC) was widely used in the 1960s and 1970s for pesticide residue analysis, but only to a limited extent since gas–liquid chromatography (GLC) and high performance liquid ...
