InstrumentName:StableIsotopeRatioMassSpectrometer

InstrumentModel:Delta V Advantage

Instrument Introduction:

The stable isotope ratio mass spectrometer was produced by Thermo Finnigan Co. in USA, which includes twoexternal equipments (Elemental Analyzer-Flash2000 and High Temperature Conversion Elemental Analyzer-TC/EA), a continuous flow interface (Conflo IV), and a host machine including a magnetic separator and ion acceptor. The C/N/S/H/O in the samples are transferred to CO2/N2/SO2/H2/CO in the external equipment, which are injected into the host machine through the Conflo for isotope analysis.
