A mist-containing gas analyzer capable of easily and accurately measuring the concentration of a substance to be measured in a target gas containing a mist of the substance to be measured. SOLUTION: A collection container 116 into which a collection liquid 2 is put, a sampling pipe 111 and a guide pipe 112 for sampling combustion exhaust gas 1 and an introduction pipe 114, and the pipes 111, 112 and 114 are sampled. An electric heater 113 that heats the tubes 111, 112, and 114 to vaporize amines and the like, and the gas 1 sampled by the tubes 111, 112, and 114 are collected in the collection liquid 2 inside the collection container 116. The feeding pipe 115 and the like to be fed, and the cleaning liquid 3 is supplied to the pipe 115, and the amines and the like adhering to the pipe 115 are fed into the collecting container 116 from the pipe 115 together with the cleaning liquid 3. A cleaning liquid introduction tube 132 and the like, and a measuring device 130 for measuring the concentration of amines and the like in the liquids 2 and 3 were provided. [Selection] Figure 1 |
