International interlaboratory study for the determination of the Fusarium mycotoxins zearalenone and deoxynivalenol in agricultural commodities
Twenty-eight laboratories from 12 different countries participated in an interlaboratory study for the determination of the Fusarium mycotoxin zearalenone (ZON) in maize and deoxynivalenol (DON) inExpand

Zearalenone in maize: stability testing and matrix characterisation of a certified reference material
Within the certification process of a reference material for the determination of the mycotoxin zearalenone (ZON) in maize, short- and long-time stability tests of naturally contaminated maize haveExpand

Limitations of the application of the Horwitz equation
We revisit the basic assumptions of the Horwitz equation using the example of mycotoxin assays. Prediction intervals from the Horwitz equation often span one order of magnitude. Including thisExpand

Trichothecenes: reference materials and method validation.
The frequent contamination of food and feed with trichothecene mycotoxins, the high consumption of these products, and the potential risk associated herewith, has led to an increasing public awareness and therefore to the establishment of measures to control the contamination. Expand

Implementing a Reference Measurement System for C-Peptide: Successes and Lessons Learned.
BACKGROUND Assessment of endogenous insulin secretion by measuring C-peptide concentrations is widely accepted. Recent studies have shown that preservation of even small amounts of endogenousExpand

Mass balance method for the SI value assignment of the purity of organic compounds.
A mass balance method is described for determining the mass fraction of the main component of a high purity organic material. The resulting assigned value is established to be traceable to the SI andExpand
