Oxidation of hydroxymethylpyrazines and hydroxylated phenyl compounds in a gas chromatography inlet†
Abstract
Large proportions of aldehydes were formed when hydroxymethylpyrazines, and benzyl- and cinnamyl alcohols were analysed by gas chromatography-mass spectrometry using a heated inlet with a previously used glass inlet liner. To avoid false reporting of non-natural compounds, any identification of aldehydes potentially formed in a GC inlet requires verification.
