The invention concerns a device and a method for the removal and determination of dissolved gases or volatile components in a liquid or in a mixture of gases in order to determine their concentration. The device consists of a cylindrical main body with permeation channels in its external surface for a carrier fluid, a permeation membrane located over the channels, carrier-fluid feed and return channels and sensors and is characterized in that the permeation channels are disposed in one or more sectors (3) on the surface of the main body (5), each sector (30) having a feed groove (2), a return groove (4) and parallel connecting channels (3) running from the feed groove (2) to the return groove (4); each sector (30) is connected by the feed groove (2) and a separate feed channel (9; 9'; etc.) to a carrier-fluid inlet (8); and each sector (30, 30') is connected by the return groove (4) and one or more return channels (10; 10'; etc.) to a carrier-fluid outlet (12). |
