FIELD: physics, measurements. ^ SUBSTANCE: invention is related to the field of metering equipment applicable to determination of released ammonia during heating or cooling of substances and their mixtures. Method includes operation of sample placement or analysed substance suspension in closed volume in gas flow, absorption of released ammonia by solution, besides, ammonia absorption is done into solution of weak acids mixture with simultaneous measurement of hydrogen index (pH), and amount of released ammonia is detected by previously built calibration chart, moreover, absorption solution used is solution of citric and oxalic acids mixture in concentration from 0.001 M to 0.1 M. ^ EFFECT: improved reliability and information value, and also simplified analysis. ^ 7 ex, 8 dwg |
