Analysis of flavonoids in tablets and urine by gas chromatography/mass spectrometry and liquid chromatography/mass spectrometry

Rapid Communications in Mass Spectrometry, 1998
A method was developed for the analysis and characterization of quercetin and kaempferol in urine following ingestion of Ginkgo biloba tablets. The method utilized gas chromatography/negative ion chemical ionization mass spectrometry of the trimethysilyl derivatives of the flavonoids.

Pyrolysis-Gas Chromatography-Mass Spectrometry

1992
Pyrolysis is the transformation of a nonvolatile compound into a volatile degradation mixture by heat in the absence of oxygen. A rate of heating to the final temperature in the millisecond range is typical for analytical pyrolysis, in contrast to the slow heating rates employed for other thermal characterization techniques, e.g., thermogravimetry (TG)

Combined gas chromatography— mass spectrometry

1994
Abstract Gas chromatography-mass spectrometry (GC-MS) remains the most effective technique for the separation, detection, and characterization of the components of complex organic mixtures (1). GC and MS are regarded as the ‘natural combination’, compared to other combined chromatographic-mass spectrometric techniques, as both display ...
