Abstract
We show a principle possibility of the determination of gases concentration s (NO, CO, Cl-2) by their affect on mixed-mode oscillations in the Belousov -Zhabotinskii (BZ) oscillating chemical reaction. These oscillations are ch aracterized by single large amplitude oscillation followed by a number of s mall amplitude oscillations. The method of the determination is based on a construction of a calibration plot given by the dependence of the number of small amplitude oscillations on gas concentration.
