FIELD: analytical methods. ^ SUBSTANCE: invention relates to analytical chemistry of inorganic compounds and comprises providing chemisorbent, filling test device therewith, exposing it to ammonia vapors, registering analytical signal with a time range 10-15 sec, and finding ammonia concentration from calibrated graph. Test device represents quartz piezoelectric resonator with its electrodes modified by sulfosalicylic acid solution so that mass of the film formed after drying-mediated removal of solvent in drying oven at 40-50C for 15-20 min at horizontal arrangement of resonator is 10-15 mug. ^ EFFECT: increased sensitivity, accuracy, rapidity, and selectivity of analysis. ^ 2 dwg, 1 tbl |
