Abstract
PURPOSE:To detect the organic gas in the titled highly accurately and safely, by aerating carrier air having a temperature which is higher than that of water to be checked by 5 deg.C or more in said water to be checked including the easily vaporizing organic gas, and measuring the accompanied organic gas. CONSTITUTION:The water to be checked 5 (wherein dissolved, easily vaporizing, organic gas such as alcohol and ester is dissoved) in a temperature preserving pot 4 is sent to a sampling part 7 by a pump 6. Meanwhile, the carrier air, which is supplied through a filter 1 and a meter 2, is heated to the temperature higher than that of the water to be checked 5 by 5 deg.C or more by a heat exchanger 3. Then the air is bubbled in the water to be checked 5. Thereafter the carrier air accompanying the dissolved, readily vaporizing, organic gas is measured by a metal oxide semiconductor gas detecting element 9 of an explosion proof type detecting part 13 (figure 8 is a temperature detecting element used for temperature compensation). The measured value of the organic gas is displayed by a recorder 11 through a control part.
