Preventing water samples evaporation is crucial for the quality of water stable isotopes analysis. Storing samples not in glass bottles, and repetitive opening of laboratory reference materials (LRM) sub-sample for daily operation, may impact the quality of analysis results. Here storing in HDPE bottles with no double cap and repetitive analysis of an LRM sub-sample replica were tested. Only this latter showed some evidence of evaporation during the observation period.

Abstract
Preventing water samples evaporation is crucial for the quality of water stable isotopes analysis. Storing samples not in glass bottles, and repetitive opening of laboratory reference materials (LRM) sub-sample for daily operation, may impact the quality of analysis results. Here storing in HDPE bottles with no double cap and repetitive analysis of an LRM sub-sample replica were tested. Only this latter showed some evidence of evaporation during the observation period.File in questo prodotto:
