Professor Shin and his team have a range of Elementar equipment installed that are in daily use. These include two elemental analyzers; the vario ISOTOPE select and the vario PYRO cube® interfaced with two IRMS (Isoprime & Isoprime100). They also have two GC5 gas chromatography inlets interfaced with two isoprime visION IRMS systems. The EA-IRMS systems are used to investigate the bulk stable isotope ratios of carbon and nitrogen as well as hydrogen and oxygen, while the GC-IRMS systems cover compound specific isotope ratios of hydrocarbons, fatty acids, sterols, and amino acids etc. Recent work determined the trophic position of various zooplankton species by measuring the nitrogen isotope ratios of specific amino acids. Professor Shin also sees an opportunity to broaden the laboratories research by investing in new instrumentation for the analysis of dissolved organic and inorganic carbon and nitrogen in a range of environmental sample matrices.
On his labs’ relationship with Elementar UK Ltd, Professor Shin had this to say:
“Elementar IRMS systems are very useful to run a wide range of sample analysis on a daily basis, whilst producing very stable isotope ratio results. We have very successfully performed compound specific isotope ratio analysis of various types of biochemical molecules and organic compounds. Our Elementar GC-IRMS systems have successfully performed novel δ13C & δ15N compound specific isotope analysis (CSIA) data for various lipids compounds and amino acids.”
