Abstract
Stable water isotopes are increasingly becoming part of routine monitoring programs that use automatic samplers. The objectives of this study were to quantify the uncertainty in isotope signatures due to the length of sample storage (1–24 d) inside autosamplers over a range of air temperatures (5–35°C) and to evaluate the effectiveness of two evaporation reduction measures (mineral oil and high density polyethylene balls). Results of the laboratory study showed that up to 11.8% of the sample volume evaporated when samples were stored in an autosampler at 35°C for 24 d. To prevent significant water isotope fractionation, samples should be retrieved from autosamplers
