ABSTRACT: A straightforward analytical method based on derivatization with fluorenylmethyloxycarbonyl chloride and liquid chromatography−mass spectrometry has been developed for the analysis of residues of glyphosate and aminomethylphosphonic acid (AMPA) in a suite of nutritional ingredients derived from soybean, corn, and sugar beet and also in cow’s milk and human breast milk. Accuracy and intermediate precision were 91−116% and
