    Abstract: Method and assembly for determining the presence of soot particles in a gas stream such as in the air. To prevent the disturbing effect of salts and the like that may be deposited on soot particles, it is proposed to introduce the soot particles into water as a suspension. The salts concerned dissolve in the water and have no effect when determining the change in optical properties resulting from the presence of the soot particles. This determination comprises in particular a light transmittance measurement. The presence of the soot particles can be determined after the gas stream is first passed through a filter, as a result of which a particle size distribution can be determined. Suspension of the soot particles can be achieved by subjecting these to a stream of steam, whereby the steam condenses on the soot particles and then causes these to precipitate out of the gas. The various processes can be expedited by using a cyclone.
