    摘要: The invention relates to a method for analyzing a gas mixture which contains a dust-like solid by separating and directing to analysis a certain quantity of the gas mixture along a sample-taking conduit, wherein a known quantity of liquid is mixed with the separated gas mixture in order to absorb the gas mixture into the liquid. The analysis is performed by analyzing the liquid which has absorbed the gas mixture. The liquid is mixed with the separated gas mixture which is being directed to analysis immediately after the gas mixture has been separated, and the separated gas mixture and the liquid are directed together along the sample-taking conduit to analysis.

    摘要: The invention relates to a nozzle for continuous separation of a representative sample from a duct-containing gas for its analysis. The nozzle has a pipe, intended to open into the sample-taking space, for continuous separation of the sample from a dust-containing gas and for directing the sample to be analyzed, and a second pipe for feeding water into the mouth of the sample-taking pipe in order to keep it clean and to mix the water with the gas sample. In order to obtain a representative sample and to ensure that the nozzle remains open, at the sample-taking end of the sample-taking pipe there is fitted a sleeve which extends somewhat beyond the pipe and encircles it, the water pipe being connected to the sleeve in order to feed water via the annular clearance between the sleeve and the sample-taking pipe to a point in front of the mouth of the sample-taking pipe, and from the inner wall of the open part of the sleeve, extending beyond the sample-taking end of the sample-taking pipe, there extends a ring-like stop oriented against the water flow, in which case a slit, transverse in relation to the gas flow direction and encircling the sample-taking mouth, is formed between the stop and the end of the pipe.
