Metrohm offers an application for the straightforward determination of the herbicide glyphosate and its primary metabolite AMPA indrinking water by ion chromatography with pulsed amperometric detection.
With a detection limit of approximately 1 μg/L, the method is sensitive enough to comply with limit values in the US, Canada, Australia, and others. A free whitepaper provides more details on the method and its application.
Glyphosate and its metabolite AMPA (aminomethylphosphonic acid) are usually determined by HPLC with post-column derivatisation and subsequent fluorescence detection (EPA Method 547), or alternatively by ion chromatography coupled with a mass-selective detector.
The white paper demonstrates that ion chromatography with pulsed amperometric detection is a viable, less expensive alternative for determining the glyphosate and AMPA content in water and foodstuffs.
