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 ...

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 ...

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 ...

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 ...

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 ...

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) ...

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 ...

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 ...

The wide range of chromatographic techniques share one common aim: to separate a material into its components. A material, your sample, is dissolved in a solvent, called the mobile phase. This mixture ...

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 ...
