This generation of IRMS technology is a universal tool for ¹³C/¹²C, and ¹⁵N/¹⁴N, ¹⁸O/¹⁶O, ³⁴S/³²S, D/H determination in both dual inlet and continuous flow modes. A wide range of detector configurations allows for the development of novel techniques. The DELTA^plusXP is a stable isotope ratio mass spectrometer for both routine and research applications.

Universal on-line gas preparation and introduction system for IRMS. An innovative tool for generating high precision on-line isotope ratio determination of gas species, waters and carbonates. The GasBench II combines dual inlet precision and accuracy with the high throughput of continuous flow technology. The various applications include, but are not limited to: water equilibration with CO₂ ¹⁸O/ ¹⁶O, carbonate ¹³C/¹²C and ¹⁸O/¹⁶O, dissolved inorganic carbon (DIC) ¹³C/¹²C, determination of ¹³C/ ¹²C of CO₂ and ¹⁵N/¹⁴N in air. The TC/EA high temperature conversion allows for direct continuous flow determination of ¹⁸O/ ¹⁶O and D/H enhancing the capabilities of the two existing QFIR conventional EA (elemental analysers) which currently permit on-line isotope ratio analysis of organic bulk samples for ¹³C/¹²C, ¹⁵N/¹⁴N and ³⁴S/ ³²S.

In addition to both stand alone and continuous flow GC operation of present technology, the Trace GC expands capabilities from the existing GC/C/TC/IRMS (gas chromatography / combustion /thermochemical pyrolysis/ isotope ratio mass spectrometer). It incorporates compound specific isotopic analysis (CSIA) from ¹³C/¹²C and ¹⁵N/¹⁴N to include ¹⁸O/ ¹⁶O and D/H.

Stable Isotope Ratio Mass Spectrometer coupled to the MAT 252 using continuous flow technology is a Hewlett Packard - HP5890 Series II gas chromatograph and a Carlo Erba Elemental Analyzer: NCS 2500.

Similar to the Trace Gas Chromatograph the HP will function in stand alone and continuous flow GC operation. The HP 5890 is also interfaced for GC/C/IRMS (gas chromatography / combustion / isotope ratio mass spectrometer). It incorporates compound specific isotopic analysis (CSIA) for ¹³C/¹²C.
