EA-IRMS

Isotope ratio mass spectrometer (IRMS) (Thermo Fisher Scientific Delta plus) coupled to an elemental analyzer (CE Instruments FLASH EA 1112NA 1500) via Conflo II to analyze the stable isotope composition of either solid or liquid samples.

Samples (solid or liquid) are combusted in an elemental analyzer; a well defined part of their combustion gases is given access via Conflo II to the mass spectrometer. This coupling allows the determination of the N-, C- or S-Isotope composition of the sample either at natural abundance or enrichment levels.
