Position Paper No. 19-03: Differing results of competent laboratories: reasons and what is “common”?
This position paper refers to possible reasons and influences on differing analytical results (although no or only few differences are expected).
Position Paper No. 19-02: Influence of sampling on the variation and validity of analytical results
This position paper refers to the influence of sampling (outside the laboratory) on the analytical result and the corresponding deviations of analytical results.
Position Paper No. 19-01: Sources of contamination of samples for analysis
This position paper is about substances (pesticides, contaminants, biocides a.o.) showing positive results in laboratory samples altough these substances were not applied deliberately.
Position Paper No. 18-01: Sample Preparation Project – Part 1
This position paper refers to the preparation and homogenisation of food samples (fruits and vegetables) for residue analyses taking – demonstrated by 5 selected products.
Position Paper No. 17-01: Phthalimid part 2 – Unavoidable Artefact!
This position paper refers to the formation of phthalimid (PI) out of phthalic anhydride (PSA) during gaschromatografic analysis, and corresponding impacts on the interpretation of results.
Position Paper No 16-05: Quantification of Acidic Herbicides
This Position Paper is related to to the quantification of Phenoxycarboxylic acids (“Acidic Herbicides”), which require an additional hydrolysis step in certain cases.
