New IRMS water standards available

New additions to our portfolio: five water standards that represent natural meterological water from around the world. These are meteoric waters that originate from precipitation such as snow and rain. This also includes water from lakes, rivers and ice melt, all of which are indirectly attributable to precipitation. Our product programme is supplemented by three enriched water standards.

     
    We are pleased to announce the expansion of our range of new water standards for the analysis of stable isotopes.

    Five standards were selected on the basis of various criteria in such a way that they optimally reflect the variation of natural isotope values on Earth.

    They are supplemented by three enriched water standards, which are preferably used in the field of biomedical research, e.g. for measuring metabolic rates and total energy consumption.

    Our standards can be used as cost-effective working reference and quality control standards for the analysis of hydrogen and oxygen isotopes in aqueous samples in a wide range of research fields such as palaeoclimatology, hydrology, oceanography and geochemistry.
