Abstract: | We show a principle possibility of the determination of gases concentrations (NO, CO, Cl(2)) by their affect on mixed-mode oscillations in the Belousov-Zhabotinskii (BZ) oscillating chemical reaction. These oscillations are characterized by single large amplitude oscillation followed by a number of small 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. |
