My first first-authored paper as a postdoc at ICTA-UAB, published in J. Chromatogr. A, deserves a thread on Bluesky as well! We selectively extract levoglucosan and its isomers from complex matrices, such as sediments, for quantification by LC-ESI-MS/MS! doi.org/10.1016/j.ch... (1/27) 🧪👩‍🔬

Levoglucosan, galactosan, and mannosan are specific biomass burning biomarkers which are generated during the pyrolysis of cellulose and hemicellulose. These biomarkers, also named monosaccharide anhydrides (MAs), are thus useful to track modern and past biomass burning. (2/27)
