Technical Note: Evaluation of between-sample memory effects in the analysis of 2H and 18O of water samples measured by laser spectroscopes

Original language description

This study evaluated between-sample memory in isotopic measurements of 2H and 18O in water samples by laser spectroscopy. Ten isotopically depleted water samples spanning a broad range of oxygen and hydrogen isotopic compositions were measured by three generations of offaxis integrated cavity output spectroscopy and cavity ringdown spectroscopy instruments. The analysis procedure encompassed small (less than 2permille for 2H and 1permille for 18O) and large (up to 201permille for 2H and 25permille for 18O) differences in isotopic compositions between adjacent sample vials. Samples were injected 18 times each, and the betweensample memory effect was quantified for each analysis run. Results showed that samples adversely affected by betweensample isotopic differences stabilised after seven-eight injections. The between-sample memory effect ranged from 14% and 9% for 2H and 18O measurements, respectively, but declined to negligible carryover (between 0.1% and 0.3% for both isotopes) when
