FIELD: analytical chemistry.
SUBSTANCE: invention relates to analytical chemistry. The chromatography-mass spectrometry method for identifying and quantifying chloroacetophenone in air during one analysis includes the analysis of an air sample taken on a concentrator containing the Tenax TA sorbent on an on-board mass spectrometer, the calculation of the concentration of chloroacetophenone is carried out by an internal standard method, as which m-nitrotoluene is used.
EFFECT: simplification of sample preparation, the process of analysis and calculations, an increase in the degree of absorption of chloroacetophenone from the air.
