Auto-deconvolution and molecular networking of gas chromatography–mass spectrometry data

open access: yesNature Biotechnology, 2020
We engineered a machine learning approach, MSHub, to enable auto-deconvolution of gas chromatography–mass spectrometry (GC–MS) data. We then designed workflows to enable the community to store, process, share, annotate, compare and perform molecular ...

Microbial Metabolomics with Gas Chromatography/Mass Spectrometry [PDF]

open access: yesAnalytical Chemistry, 2006
An analytical method was set up suitable for the analysis of microbial metabolomes, consisting of an oximation and silylation derivatization reaction and subsequent analysis by gas chromatography coupled to mass spectrometry. Microbial matrixes contain many compounds that potentially interfere with either the derivatization procedure or analysis, such ...
