German standard methods for the examination of water, waste water and sludge - Jointly determinable substances (group F) - Part 22: Determination of Glyphosate and Aminomethyl phosphic acid (AMPA) by high performance liquid chromatography (HPLC), post-column derivatization and fluorescence detection (F 22)

Summary
The document describes a chemical method for the determination of Glyphosate and AMPA in drinking, ground and surface water. Two methods for the pretreatment of the samples are described. Glyphosate and AMPA are seperated at a cation exchanger by isocratic HPLC and directly supplied to a two-phase post-column derivatization. At the first step Glyhosate is converted into Gylcine. At the second step Glyconme and AMPA are derivated in the presence of Dimethylaminoethanthiol-Hydrochlodrid. The resulting Isoindolderivates are detected by fluorescence measurement.
