For the first time, glyphosate determination and that of its primary metabolite AMPA in drinking water using IC with pulsed amperometric detection (flexIPAD) in the low µg/L range are shown. Compared to HPLC analysis with a mass-selective detector, it is a very cost-effective method for determining the glyphosate and AMPA content in water and foodstuffs. With a detection limit at approx. 1 µg/L, compliance with limit values for glyphosate can be monitored in the USA, Canada, and Australia, among others.
