Аннотация:The method for the determination of dissolved methane in water using the system based on a tubularselective membrane permeable to volatile organic substances and impermeable to liquid water is proposed.Purified air is passed through the membrane tube immersed in water. The air inside the tube is saturated withmethane dissolved in water, which diffuses through the tube wall. Methane concentration is measured in theair passing through the membrane tube using a semiconductor metal oxide sensor. The sensitivity thresholdand the response time of the system are estimated.
