| abstract |
The invention concerns a device (1, 101) for extracting at least one gas dissolved in a liquid, the device comprising (i) at least one gas/liquid separating membrane (3, 103); and a method for continuous measurement of the concentration or partial pressure of at least one gas dissolved in a liquid, the method comprising placing a gas/liquid separation device, comprising at least one membrane, in contact with a liquid, for which the concentration of at least one dissolved gas is to be measured, separating at least one gas dissolved in the liquid through the membrane or membranes of the gas/liquid separation device, measuring the flow by diffusion and/or permeation through the membrane or membranes, and calculating the concentration or the partial pressure of the gas previously dissolved in the liquid on the basis of the diffusion and/or permeation flow. |
