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 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 ...

THE heating of polyunsaturated fatty acids in strong alkali is known to cause re-arrangement of the double bonds to form a conjugated system 1. The effect of this isomerization on the behaviour of ...

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 ...

In the search and recovery of human remains during mass disasters, homicides, and missing persons investigations, the odor evolved from decomposing bodies is crucial in the search process. One ...

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 ...

Annals of Botany, New Series, Vol. 37, No. 149 (January 1973), pp. 167-183 (17 pages) A previous investigation of volatile isothiocyanates had produced evidence for the existence of two geographic ...

LCGC International spoke with Thomas Letzel about the key developments he expects to influence chromatography in 2026.

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 ...
