FIELD: organic compounds, analytical chemistry.
SUBSTANCE: invention relates to separation and analysis of organic compounds and can be used in analysis of air in working zone of plants in manufacturing dyes, varnishes and pharmaceutical production. Method involves sampling, preparing the sensor, determination of (C2-C5)-alkyl acetates by the modified piezoelectric vibrator that is modified with an active sorbent polyethylene glycol sebacate with mass 10-25 mcg. Invention provides reducing limits for detecting (C2-C5)-alkyl acetates, enhancing sensitivity of analysis and simplifying equipments used.
EFFECT: improved method for analysis.
