Creation and experience of using a multi-method for controlling pesticides in grain on the territory of the Russian Federation

Abstract

This article is devoted to the development and testing of a multimethod for determining pesticides in grain, legume and oil crops using gas chromatography with mass spectrometric detection. Optimal parameters of sample preparation and chromatograph-mass spectrometric determination for the simultaneous analysis of 430 substances were established. Metrological characteristics such as uncertainty, repeatability and precision were calculated. The method was tested at the Moscow branch of the All-Russian Research Institute of Animal Husbandry on 120 samples of grain, legume and oil crops; these data are also presented in the article.
