Thermo Scientific GasBench II IRMS universal on-line sample preparation and introduction system. The gas chromatography-based GasBench II system facilitates high-precision on-line isotope and molecular ratio determination of headspace samples, including water equilibration, carbonates, and atmospheric gases (e.g. CO2, N2). A reference gas injection system allows the precision and accuracy of a dual inlet system to be realized on a continuous-flow IRMS system. It is capable of Measurement of the D/H and 18O/16O ratios in water, dissolved inorganic carbon, 18O/16O and 13C/12C measurements of carbonates and 13C/12C and 15N/14N ratios in air.
