Retention time prediction is dead, long live retention order index prediction! | Lehrstuhl Bioinformatik Jena

We just solved a problem that I never wanted to solve: That is, transferable retention time prediction of small molecules. They say that the best king is someone who does not want to be king; so maybe, the best problem solver is someone who does not want to solve the problem? Not sure about that.

Let me explain in the following #thread why the (auto-)citation of Davtian et al. (2018) Organic Geochemistry—my second first-authored #PhD #scientific #publication—by De Jonge et al. (2024) Geochemistry, Geophysics, Geosystems matters to me and my current CEREGE colleagues at CEREGE

The importance of mass accuracy in selected ion monitoring analysis of branched and isoprenoid tetraethers

Among the new proxies based on the distribution of glycerol dialkyl glycerol tetraethers (GDGTs), the BIT index (Branched and Isoprenoid Tetraether in…

I am so glad to be one of the two ICTA-UAB representants—the other is Joan Villanueva—for the interlaboratory #study led by Cindy De Jonge and Francien Peterse!

Selective extraction of levoglucosan and its isomers from complex matrices using ligand exchange-solid phase extraction for analysis by liquid chromatography-electrospray ionization-tandem mass spectrometry

The analysis of trace quantities of monosaccharide anhydrides (MAs) in sediments is complicated by the lack of fast and reliable technologies to selec…
