Isotope Ratio Mass Spectrometry (IRMS)


The Finnigan Mat (F-Mat) DeltaPlus and DeltaPlusXL Spectrometers are the central components of EQAL. The F-Mat DeltaPlusXL IRMS is equipped with a NC-2500 elemental analyzer, TC/EA, and GC-C (Gas Chromatography-Combustion) interfaces.

This versatile instrument allows automated analyses of a comprehensive suite of stable isotopes, including the major elements that commonly used in biological and environmental research. Continuous-flow (ConFlo) isotopic measurement of 13C/12C, 15N/14N, 2H/1H, and 18O/16O in solid or liquid samples is performed using an IRMS equipped with a NC-2500 Elemental Analyzer and a High Temperature Conversion Elemental Analyzer (TC/EA).

Gas Bench II interfaces combined with injection interface enables the simultaneous measurement of δ13C, δ15N and δ18O of dissolved gases in water samples. Gas Bench interface, on the other hand, with the Combi PAL autosampler, is also popularly used for simultaneous measurement of 13C and 18O isotopic compositions of the CO2 from biological breaths as well as carbonates from geological and soil deposits.
