The results of research of the method of determination of toxic substances in the composition of gas-air medium providing high efficiency of continuous monitoring, control and management of the content of harmful components in gas mixtures on the examples of continuous monitoring of the content of mercaptans in the natural gas of technological lines of gas processing and chemical plants are presented. The basic regularities of the methods of direct and indirect coulometry in determining the concentration of mercaptans in a gas mixture have been studied. As a result of the study of the measurement conversion processes occurring in electrochemical cells with sensitive elements - gas-diffusion hydrophobised electrodes, the choice of a promising design of the gas analyser intended for determining the concentration of mercaptans in natural gas in the range of 0-100 mg/m3 and hydrogen sulphide in the range of 0-50 mg/m3 has been justified.
