Analysis of volatile organic compounds in air by gas chromatography with thermal desorption cold‐trap injection and atomic emission and mass selective detection

Some unique properties of gas chromatography coupled with atomic-emission detection

“…This should be an attractive feature in many studies, because [82] labeling with radioactive isotopes can thus be avoided. Furthermore, unlike in mass spectrometry, an isotope-selective chromatogram is obtained and the analyst need not evaluate every single mass spectrum searching for labeled compounds.…”

Injection by Programmed Temperature Vaporization Injection (PTV) of Gaseous Samples for Gas Chromatography - Atomic Emission Spectrometry (GC-AED)

“…Although Yamashita and co-workers [12] used Tenax GC as an adsorbent to concentrate volatile organic compounds in air, they employed a secondary cryogenic step for gas desorption, increasing the complexity of the system. This paper describes the use of sorbent trap sample focusing with programmed vaporization injection (PTV) for GC-AED for large volume injection of gaseous samples requiring no secondary cryofocusing.…”
