Abstract

FIELD: analytic instrumentation. SUBSTANCE: process may find use for determination of concentrations of vapours of different organic solvents in gas mixtures as well as for manufacture of gas analyzing devices warning about change of concentration of these solvents. Hydrophobic adhesion layer and crystallohydrate of metal of transition series are applied in sequence on to indicator element and are dried at temperatures from 20 up to 50 C for the coures of not less than 24 h. For determination of methanol vapours compound based of phenolformaldehyde resin and cobalt hexahydrate CoCl•6HO is sequentially applied on indicator element. EFFECT: manufacture of indicator element sensitive to vapours of different organic solvents with prolonged service life. 2 cl
