A highly sensitive pre-column derivatization HPLC method for simultaneous determination of glyphosate (GLYP) and its major metabolite aminomethylphosphonic acid (AMPA) in soybean samples was developed. The analytes were labeled with a novel fluorescent labeling reagent 3,6-dimethoxy-9-phenyl-9H-carbazole-1-s.

Analysis and degradation study of glyphosate and of aminomethylphosphonic acid in natural waters by means of polymeric and ion-exchange solid-phase extraction columns followed by ion chromatography-post-column derivatization with fluorescence detection.
Derivatization, prior to the chromatographic analysis of the particularly polar herbicide - N-(phosphonomethyl)glycine (glyphosate, GLYP) and its main metabolite aminomethylphosphonic acid (AMPA)) - proved to be a key step: also in cases applying liquid chromatographic techniques.In this paper the analytical proposals for GLYP and AMPA are reviewed: performing analyses by chromatography.
Analysis of glyphosate and aminomethylphosphonic acid in leaves from Coffea arabica using High performance liquid chromatography with quadrupole mass spectrometry.
Pesticide properties for aminomethylphosphonic acid, including approvals, environmental fate, eco-toxicity and human health issues.
Summary. The object of this work was to optimize and validate an analytical method for the analysis of glyphosate and its main metabolite AMPA (aminomethylphosphonic acid) in natural and drinking water, for sanitary control.
Background: Although glyphosate is widely used in agriculture, information on its residue level in soils remains scarce partly because of the difficulty in its analysis. Objective: Develop and validate a method to directly analyze glyphosate and its metabolite aminomethylphosphonic acid (AMPA) in soil. Method: Soils were extracted with 0.6 M KOH solution, and coextracted interferences were.
Aminomethylphosphonic acid (AMPA) is the most frequently detected metabolite of glyphosate in plants. The objective of this study was to determine if there is any correlation of metabolism of glyphosate to AMPA in different plant species and their natural level of resistance to glyphosate. Greenhouse studies were conducted to determine the.

After 24 hours, the reaction is stopped and stabilized by adding 2% phosphoric acid. All tubes are stored in the dark until analyzed. A 5.5-mL aliquot of each sample and the matching standard-addition sample are diluted 1:1 with reagent water in autosampler vials, capped, and placed in the tray of the autosampler.
AMPA, aminomethylphosphonic acid, is a degradation product of glyphosate. Since the introduction of glyphosate resistant (round-up ready) corn and soybeans glyphosate has become the most widely used herbicide in the world.The CAS number is the substance numerical identifier assigned by the Chemical Abstracts Service, a division of the American Chemical Society, to substances registered in the CAS registry database. A substance identified primarily by an EC or list number may be linked with more than one CAS number, or with CAS numbers that have been deleted.Glyphosate Herbicide Analysis Columns Pickering Laboratories cation-exchange Glyphosate column is designed and tested for analysis of Glyphosate and its primary metabolite Aminomethylphosphonic acid (AMPA). This short, isocratic method provides separation of the peaks of interest.
