Abstract
For the continuous quantitative detection of volatile substances in liquids, in particular halogenated hydrocarbons in process water or effluent, the invention proposes a suitable process by which the liquid is passed through a liquid-impermeable but gas-permeable membrane, such that the strippable substances in the liquid penetrate the membrane in their gas phase and are fed through a measuring cell. A device for performing the process is characterized by a flow chamber provided with a liquid-impermeable but gas-permeable membrane for the liquids under test and by a measuring cell arranged on the side of the membrane facing away from the low chamber for the substances under test.
