HPLC determination of glyphosate,
aminomethylphosphonic acid and glufosinate using a porous graphitized hypercarb
sorbent
Abstract
A HPLC method for the determination of
glyphosate, aminomethylphosphonic acid and glufosinate is proposed using a
gradient separation of analytes on a porous graphitized carbon sorbent
Hypercarb and an aqueous solution of ammonium formate / ammonia as a mobile
phase. Analytes were detected using quadrupole and triple-quadrupole mass
spectrometers. To increase the retention of the analytes, the chromatographic
column was washed with water before injecting the sample solution. This method
makes it possible to increase the retention coefficients of analytes by 3-4
times in comparison with the analogs described in the literature.
Key words: liquid chromatography, mass
spectrometry, porous graphitized carbon sorbent Hypercarb, glyphosate,
glufosinate, aminomethylphosphonic acid.
