Abstract

The gas analysis apparatus is supplied with a sample gas by a gas sampling device (5). The sample gas is sucked into an ejector (3) in which it is mixed with washing water from a tank (1) and the resultant gas/water mixture is supplied to a water separator (7). The water separator (7) separates the water, together with any dust and corrosive soluble substances, from the gas, and supplies the purified sample gas to a gas analyser (10). The sample gas from the analyser (10), as well as gas which has bypassed the analyser (10) by way of the line (15), is fed back to the tank (1) for the purpose of balancing the concentration of dissolved gases in the water supplied to the ejector (3) with the concentration of the sample gas. <IMAGE>
