Summary:The 18O/16O ratios in water have been determined by a technique using guanidine hydroxide. A CO2 fractionation factor of 1.04143 has been determined using these values and 18O/16O ratios obtained by equilibration of CO2 with excess water. The results are in good agreement with published literature values. [A.J.B.]
