Glyphosate is applied in … WebIn analytical studies for glyphosate contamination, it is common-place to analyze for both parent glyphosate and AMPA. Glypho-sate is a small, polar molecule (log P -3.1) and does not contain a chromophore. Retention and detection are therefore challenging. In this study we have developed two approaches to analyzing glyphosate and AMPA by LC/MS/MS.
WebMeasured concentrations of glyphosate and AMPA ranged from 1.6 to 13 μg L-1 and 0.50 to 2.5 μg L-1, respectively.
