It has been established that for determination of CO, chlorine and hydrogen in their gas mixtures it is necessary to use Ni (OH) 2 films of different thicknesses using filter elements. On the basis of WO3 / Pd and NiOOH films, visual sensors and laboratory models of H2 and CO2 selective determination sensors were developed; The sensitivity of the sensors to these gases was ~ 1-2 vol.% (for visual sensors) and 0.01-1.1 vol.% (for laboratory models). Metrological support of the procedure for determination of CO, chlorine and hydrogen in gas mixtures and quality control of films for sensory elements have been developed.
