Abstract

This report describes the preparation of a 4-deoxynivalenol (DON) calibrant (IRMM-315) and a nivalenol (NIV) calibrant (IRMM-316) and the certification of their content (mass fraction) in the solution.
The preparation of the calibrants, the homogeneity and stability studies and the characterisation with a discussion of the results is described hereafter. Uncertainties were calculated in compliance with the Guide to the Expression of Uncertainty in Measurement (GUM) [1] and include uncertainties due to the processing, possible heterogeneity and instability.
The certified mass fractions above correlate to concentrations (not certified) of 19.7 +/- 0.6 mu g/mL for IRMM-315 and 18.8 +/- 0.7 mu g/mL for IRMM-316, at 20 °C and a density for acetonitrile of 0.783 kg/dm.
