Isotope Ratio Mass Spectrometers
After 27 years of service, the MAT 252 has now entered retirement. As such, the lab will no longer be able to perform sulfur analysis.
The DeltaVPlus I is interfaced with the EA for bulk analysis of solid samples for 13C/12C and 15N/14N, and with the GasBench for 13C/12C and 18O/16O of carbonates after treatment with phosphoric acid. It may also be interfaced with the TIC/TOC analyzer for 13C/12C of aqueous samples. Reference and sample gases are introduced via a ConFlo III interface.
The DeltaVPlus II is interfaced with an Agilent 6890N GC for compound specific isotope analysis via a GC Combustion interface, and with a TC/EA for bulk analysis of 2H/1H and 18O/16O of solid samples. This IRMS also has a dual inlet.
