Determination of pesticides in drinking water by AMD

A method is described for the identification and quantification of active ingredients of plant protecting agents in ground, drinking and mineral water. The analysis method has been accepted as German Standard Method DIN 38407, Part 11.
After extraction and enrichment of the pesticides from the water sample with solid phase extraction, the extract is chromatographed on silica gel by automated multiple development (AMD). Detection of the pesticides is performed by UV multi-wavelenght scanning. In-situ UV spectra are taken for further confirmation of positive results.
Following the strategy described in the pdf, it is possible do distinguish practically all non-volatile water extractable active ingredients of plant protecting agents on the market. The suitability of this method was proved for more than 265 pesticides.
