New Frontiers in Compound-Specific δ2H Analysis
2021
Summary Elementar UK Ltd present present two pioneering new techniques for the analysis of larger and/or more polar organic molecules of biogeochemical interest which are traditionally considered unamenable for gas chromatography stable isotope ratio mass spectrometry (GC-IRMS) analysis, which have been developed by and in collaboratoration with Elementar GC-IRMS users from a variety of laboratories. This includes a rapid one-step derivatization procedure for the isotope analysis of the non-exchangeable hydrogen in mono and disaccharides and subsequent conversion to H2 by chromium reduction ( Abrahim et al, 2020 ), and the development of a high-temperature GC-IRMS (HTGC-IRMS) methodology employed for the analysis of a suite of compounds of interest ( Lengger et al., 2021 ).
