• A rapid and precise method of<SUP>18</SUP> 0 analysis for milligram quantities of water by using a modified CO2-H2O equilibration technique at the temperature of 1210°Cand1410°Chas been developed. The reproducibility in<SUP>18</SUP> 0 analyses is found to be±0.1‰which is compared favorably with the methods reported previously. There are no measurable errors due to the memory effect and oxygen isotope exchange between CO2-H2O mixture and instrument glass.An aliquot of a water sample equilibrated with CO2 for<SUP>18</SUP> 0 analysis can be used subsequently for D analysis.
