摘要：
FIELD: chemistry.SUBSTANCE: invention relates to the field of analytical chemistry and can be used to identify impurities, in particular microimpurities related to the main component of the test substance, by chromatography-mass spectrometry using derivatization. Method for identifying the impurity of the test substance, which is related to its main component, consists in the fact that the main component of the test substance is initially identified, then the experimental values of the retention times or retention indices, of the main and impurity components in the test substance are determined using a chromatography-mass spectrometer, as well as their mass spectra, an identifiable impurity is detected, among various impurity components, with various identification variants that include a substance related to the main component, further, the main component of the test substance is derivatized by a method that allows one of the identifiable impurity variants to be obtained from it, then, by using a chromatogra
