Except for ammonium, pasteurization does not produce detectable concentration changes, thus it can be applied to field samples for long term storage at ambient temperature.
Highlights ► Pasteurization to prepare nutrients reference material and to preserve field samples. ► Homogeneity and stability studies better than a few ten nanomoles. ► Production of samples for inter-laboratory exercises as a robust method validation. Keywords Figures and tables from this article:
