The mass of these fragments is then measured and the resulting graph is analysed to identify exactly what materials are present. The GC-MS method was used to identify the presence of Bakelite in ...

A gas chromatograph mass spectrometer combines gas chromatography and mass spectrometry to identify and quantify substances. The device separates the substance into components which are detected ...

Low-pressure gas chromatography (LPGC) paired with quadrupole tandem mass spectrometry (MS-MS) can significantly shorten the time required to analyze complicated mixtures using gas chromatography (GC) ...

ACETYLCHOLINE was first identified in animal tissue by Dale and Dudley 1. They isolated acetylcholine as the double choline–acetylcholine dichloroplatinate from 40 kg of horse spleen. Its ...

The Pegasus 4D GCxGC-TOFMS is a Comprehensive Two-Dimensional Gas Chromatography with Time-of-Flight Mass Spectrometer. GCxGC, combined with the Pegasus HT TOFMS, changes the dynamic when analyzing ...

This module focuses on mass spectrometry, the reasons for using the technique and the data generated. The course reviews the types of mass spectrometers available that are hyphenated to GC and looks ...
