FIELD: analysis of gas atmosphere carrying organic compounds. SUBSTANCE: invention can be employed to raise selectivity while analyzing multicomponent mixtures. Matrix piezosorption detection cell incorporates case with branch pipes that houses number of sensors with sensitive film coats to fix key components of gas mixture, aids to record analytical signal of response of individual sensors. Cell comes in the form of cylinder with two branch pipes placed perpendicular one another and utilized to inject liquid or gaseous samples. Holders for 6 piezosensors with different films of sorbents are positioned around cover. Substrate is brought into cell to analyze liquid samples. EFFECT: simplified conditions of detection in matrix of sensors, widened potential for use for analysis of both gaseous and liquid samples. 1 cl, 3 dwg, 1 tbl
