Earth System Center for Stable Isotopic Studies

The Earth System Center for Stable Isotopic Studies, ESCSIS, a Yale Institute for Biospheric Studies research center, is a facility for the study of light stable isotopes, mainly 13C, 15N, 18O, and DH, at Yale University. Researchers have access to three continuous flow stable isotope ratio mass spectrometers, with associated peripherals, and one classic (Apple ][e controlled) dual inlet set up.

 

Stable Isotope Ratio Mass Spectrometers and Peripherals

ThermoFinnigan MAT 253
  • Configured for CO2, O2, N2/CO or H2. Routinely run CO2 or H2.
  • Continuos flow and Dual-Inlet
  • Interfaced with GCC III and Trace GC (compound specific)
  • Interfaced with H-device (DH on water)
  • Autosampler available
  • Controlled with Isodat 2.0
ThermoFinnigan DeltaPlus XP
  • Universal cups + H2--any gas within mass range. Routinely run CO2, CO, H2, or even O2 (18O)
  • Continous flow or Dual-Inlet
  • Interfaced with TC/EA (carbon reduction/pyrolysis)
  • Interfaced with GasBench (headspace sampling) (water, carbonates, etc.)
  • Autosamplers available
  • Controlled with Isodat 2.0
ThermoFinnigan DeltaPlus Advantage
  • Universal cups (no H2 )--any gas within mass range. Routinely run CO2, N2--periodically SO2
  • Continous flow
