Theory of Operation:
- Isotope-ratio mass spectrometry (IRMS) is a specialization of mass spectrometry, in which mass spectrometric methods are used to measure the relative abundance of non-radioactive isotopes in a given sample.
- Coupled with the Trace GC Ultra, GC IsoLink, and ConFlo IV, the Delta V Advantage Isotope Ratio MS can measure the isotope ratios of a complex mixture of gases after they have been separated and then converted into simple gases.
- For carbon isotopic analysis, the analysis requires the separation of hydrocarbon gases on a gas chromatograph followed by combustion of products, which are then sent to the isotope ratio mass spectrometer for ionization, separation, and detection. For low-concentration gases, concentration enrichment on a cold trap using liquid nitrogen may be required.
- For hydrogen isotopic analysis, the analysis depends on the separation of hydrocarbon gases on a gas chromatograph followed by pyrolysis of products, which are then sent to the isotope ratio mass spectrometer for ionization, separation, and detection.
