High Temperature Conversion Elemental Analyzer (TC/EA)-IRMS
DI –IRMS

The laboratory has a Thermo Finnigan Delta plus XP isotope ratio mass spectrometer (IRMS), which is specially designed for measurement of light environmental stable isotopes 2H, 13C, 15N, 18O, 34S is a sensitive and selective instrument with application in hydrology, geology, environmental protection, radwaste management.

The IRMS is a universal tool for 13C/12C, 15N/14N, 18O/16O, 34S/32S, and 2H /1H determination in dual inlet and continuous flow modes.

Prior to stable isotope ratio measurements different samples has to be brought in gaseous form. A host of preparation methods have been developed and improved to convert different sample compounds to an appropriate gas including H2,CO, CO2, N2, and SO2.
