The patent concerns a method of detecting and measuring the quantity of a gas dissolved in a liquid. This comprises flowing a carrier gas for displacing the dissolved gas from the liquid over a flowing body of the liquid in a confined cylindrical zone at carrier gas-to-liquid ratios of from 10 to 1 through 1 to 2 and flow rates therefor of up to about 100 cc per minute, continuously lifting films of the liquid into and across the flowing carrier gas to effect displacement of the dissolved gas from the liquid and formation of a mixture of the carrier gas and displaced dissolved gas and flowing said mixed gas through an operating thermal conductivity cell to relate the thermal conductivity of said mixed gas to that of the carrier gas.
