Abstract

An automatic CO2-water equilibration set-up originally designed for δ18O measurement of water samples was employed for δD analysis using the lately established H2-water equilibration method without any modification of the instrument. No special skill is needed and the time required for both δD and δ18O analyses of 24 waters was only 15 h. Long-term reproducibilities were ± 1.5 and ±0.16% for δD and δ18O analyses, respectively. This method is very suitable for multi-water analyses.
