Development of certified calibrants for the analysis of zearalenone and B-trichothecenes.

Recent intercomparison studies have clearly shown that the use of common calibrants does considerably improve the between laboratory comparability of measurement results. However, there is still a lack of certified calibrants within the field of mycotoxin analysis. Therefore, two EC-funded projects have been carried out with the aim to investigate the feasibility for the production of calibrants with certified concentrations of B-trichothecenes and for the production of a certified calibrant of zearalenone in acetonitrile.
