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

An off-line technique is described for the preparation of H 2 from water prior to analysis of d 2 H by dual-inlet isotope ratio mass spectrometry. H 2 is produced from sample water by reaction with LiAlH 4 . This provides a rapid and inexpensive method for the analysis of d 2 H in small (10 mL) samp
