The present invention is to provide a mist-containing gas analysis device that can simply and accurately measure a concentration of a measurement-target substance in a target gas which contains a mist of the measurement-target substance. The device includes: a measuring instrument (145, 144, 146 and 147) that measures a pressure, a temperature, a flow rate and water content of a combustion exhaust gas (1); a collection container (116) that contains collection liquid (2); a sampling tube (111) and a guide tube (112) through which the combustion exhaust gas is suctioned by a suction blower (122), and is sampled and fed into the collection liquid in the collection container; an arithmetic and control device (140) that controls the suction blower in such a manner that a suction velocity of the combustion exhaust gas being suctioned by the suction blower is within a predetermined ratio with respect to a combustion exhaust gas flow velocity which is calculated based on the measured values; liquid aliquot taking means for taking an aliquot of the liquid in the collection container; and a measuring device (130) that measures a concentration of the measurement-target substance in the aliquot of the liquid taken by the liquid aliquot taking means. |
