Gas chromatographic method for quantifying organophosphorus agents using an internal standard methylphosphonic acid dialkyl ester

摘要

FIELD: chemistry.;SUBSTANCE: gas chromatographic method for quantitative determination of organophosphorus toxic substances sarin, soman, VX, involves an internal standard method for quantitative determination of organophosphorus toxic substances. The internal standard used is State standard samples of dialkyl esters of methyl-phosphoric acid. Also, the gas chromatographic method for quantitative determination of organophosphorus toxic substances employs a flame photometric detector on a phosphorus channel with wavelength λ=525 nm.;EFFECT: quantitative determination under uniformity of measurements with sufficient reliability and accuracy of obtained results.;2 cl, 5 tbl, 3 dwg
