Abstract:
1. A method of determining the presence or amount of N-acetylglyphosate in a test sample comprising: a) providing said test sample suspected of containing said N-acetylglyphosate; b) extracting a composition comprising the N-acetylglyphosate from said test sample; c) adding a sufficient concentration of phosphoric acid to the composition comprising the N-acetylglyphosate, wherein said sufficient concentration allows for an improved response and linearity of N-acetylglyphosate during detection; d) chromatographically separating said N-acetylglyphosate from other constituents in said composition by a high performance liquid chromatography (HPLC) column; and, e) analyzing by a tandem mass spectrometer the chromatographically separated N-acetylglyphosate to determine the presence or amount of the N-acetylglyphosate in the test sample.
