Spectrometry and Spectroscopy

Elemental Analyzer – Isotope Ratio Mass Spectrometry (EA-IRMS) system – Thermo Scientific Flash 2000 EA, Delta V Plus IRMS

Trace1310 gas chromatograph, Isolink II, ConFlo IV, and a Delta V Plus IRMS.

Trace1310 gas chromatograph, Isolink II, ConFlo IV, and a Delta V Plus IRMS

This EA-IRMS system can simultaneously measure δ13C and δ15N of bulk organic material, as well as quantify %-Carbon and %-Nitrogen of the sample. Potential samples include sediments, plant tissues, bone, or other biological materials.

Features

  • Flash 2000 EA
    • Combustion reactor packed with silvered cobaltous oxide and chromium oxide
    • Reduction reactor packed with reduced copper
    • Organic material is quantitatively converted to CO2 and N2 gas for IRMS analysis
    • Delta V Plus IRMS
    • Five faraday collectors configured to measure stable isotopes of C, H, N, O
    • Upper mass limit of 96 amu, mass resolution of 110 at 10% peak height
  • Ideal sample mass depends on expected sample carbon and nitrogen content. For example, sediments generally require 25 mg of material to get reliable measurements.
