Dave TabbWhy has GC-MS (gas chromatography- electron impact ioniation- mass spectrometry) had such enduring value for the field of metabolomics? How do we identify metabolites based on mass spectrometry data?
I hope you'll enjoy this video explaining the basics of GC-MS and the spectral library methods we use for explaining these spectra!

Andy NapperJust spent four hours trying to make a leak-free seal between a tank of UHP He and a regulator.
Turns out the seat in the tank was corroded and no matter how tight I attached the regulator, nothing was going to work.
(Luckily my wife suggested I try another regulator, and w/in ten mins of my conversation with her I realized I was on a fool's errand.)
I need a beer. π»#GCMS
Markus Witzlerπ¨ #publication alert!
Just a few days into the new year and we already have a published #paper first-authored by our PhD candidate Sarah. π
It is the first study on the volatile emissions of Synchytrium endobioticum (potato wart disease) on potatoes. We identified seven possible marker compounds using TD-GC-MS and #chemometrics.
S. endobioticum is a highly potent fungus classified as a quarantine pathogen in the EU, since it can affect #potato fields for more than 40 years.
Our research offers new insights into the volatilome and may enable future screening methods for potato diseases.

Diagnostic volatile organic compounds for potato wart disease: a GC-MS based chemometric approach - Journal of Plant Diseases and Protection
Volatile organic compounds (VOCs) can serve as sensitive indicators of plant health and pathogen infection. In this study, gas chromatographyβmass spectrometry combined with multivariate chemometric analysis was applied to identify VOC patterns specific to potato wart disease caused by the pathogen Synchytrium endobioticum. Healthy and artificially infected potato tubers were analyzed under controlled conditions, and the resulting chromatographic data were processed using a Python-based workflow integrating data merging, preprocessing, principal component analysis, and linear discriminant analysis. The chemometric models successfully distinguished infected from healthy tubers. Seven compounds, 1-methoxy-3-methylbutane, 3-methyl-1-butanol, 2-methyl-1-butanol, 2,3-butanediol, prenyl ethyl ether, styrene, and solavetivone, were identified as indicative for infection. In addition, a mass-specific evaluation demonstrated that discrimination is possible using selected ion fragments alone, providing a basis for simplified on-site applications. This study presents the first characterization of a volatile fingerprint for S. endobioticum infection and establishes a robust, time-efficient workflow for non-invasive detection of quarantine pathogens in potato crops.
