Thermo Scientific™ Related applications: Industrial Mass SpectrometryAchieve continuous-flow online analysis of oxygen and hydrogen isotope ratios with the Thermo Scientific™ TC/EA high temperature conversion elemental analyzer. For many years, measurement of 18O/16O and D/H ratios has been limited to offline sample preparation. The TC/EA high temperature conversion elemental analyzer changes that; it provides the benefits of continuous-flow IRMS to online oxygen and hydrogen isotope ratio analysis for all organic and some inorganic samples. The system uses high-temperature pyrolysis to convert oxygen to CO and hydrogen to H2. The gases are separated by isothermal gas chromatography and measured against reference gas.
The TC/EA analyzer can be connected to any current Thermo Scientific™ IRMS equipped for continuous-flow applications. If hydrogen isotope ratios are to be analyzed, the IRMS must be equipped with an energy filter to suppress 4He+ ions on the DH collector (Thermo Scientific™ MAT 253™, DELTA V Plus™, DELTA V Advantage™ systems). A differential pumping system is required.
