<p>1529690 Continuous gas sampling PHILIPS ELECTRONIC AND ASSOCIATED INDUSTRIES Ltd 17 Oct 1975 [22 Oct 1974] 42696/75 Heading G1B Apparatus for continuous determination of a gaseous component in a gas mixture, for example of hydrogen thionide in polluted air comprises absorption member 3, means 1, 2 for supplying respectively a constant stream of the gas mixture and a constant stream of absorption liquid for absorbing the component to be determined to member 3, a conduit leading from member 3 to one of a pair of doubly communicating reservoirs 12, 13, a gas outlet from reservoir 13 to line 7, a liquid suction opening from reservoir 12 for maintenance of a constant liquid level in the reservoirs, means for discharge of liquid from reservoir 13 and supplying it at constant rate to detection 10 for determination of the component, means 14 etc. for supplying to reservoir 12 a constant stream of pure solvent of the absorption liquid, the arrangement in use being such that the rate of supply of liquid from the reservoir 13 to the detector 10 is less than the rate of supply to reservoirs but greater than the supply from the absorption member 3 to the reservoirs.</p> |
