Of all the elements, hydrogen has the largest naturally occurring variations in the ratio of its stable isotopes (D/H). It is for this reason that there has been a strong desire to add hydrogen to the list of elements amenable to isotope ratio monitoring gas chromatography/mass spectrometry (irm-GC/
Continuous-flow isotope ratio mass spectrometry (CF-IRMS) has been shown to minimize sample preparation and reduce the sample size requirements and time for the determination of carbon and nitrogen. An inexpensive CF inlet was developed for the determination of the 18O isotopic abundance in CO2. Ini
We have evaluated the use of nickel wool, nickelized carbon and a combination of both as catalysts in the on-line reduction of H,O, in a tubular micro-furnace, for 8% and 8"O measurement by continuous-fiow k~tope ratio mas spectrometry (CF-IRMS). The used was of a novel design whicb gives adequate r
