For a generation or more, the mass spectrometry that developed at the frontier of molecular biology was worlds apart from isotope ratio mass spectrometry, a label-free approach done on optimized gas-source magnetic sector instruments. Recent studies

Isotopomer approaches to the detection of anaerobic oxidation of natural gas hydrocarbons

Autor: Yuichiro Ueno, Naohiro Yoshida, Alexis Gilbert, Maxime Julien

Hydrocarbons are the main constituents of natural gas. Their chemical and isotope abundance is a window to biogeochemical processes occurring in the subsurface. Stable isotopes of natural gas hydrocarbons are traditionally measured through compound-s
