Zheng-Hua Li sits at the console for the Finnigan Deltaplus XL Dual Inlet Stable Isotope Ratio Mass Spectrometer with TC/EA and GC-C. This spectrometer, and a Finnigan Deltaplus Spectrometer with Equilibrator and CarboFlo, are used to analyze stable H, C, O, N, and S isotopic compositions in various organic and inorganic materials.
