Abstract

A scattered light method for measuring particle-dependent parameters of gases, in particular particle-dependent parameters of internal combustion engine exhaust gases or other colloids, includes introducing a particle-containing gas into a measuring chamber; emitting a light beam into the measuring chamber; receiving light scattered by the particles using at least two scattered light sensors, the scattered light sensors generating scattered light sensor signals, each being a function of the light received by the respective scattered light sensor; determining an average particle size from the scattered light sensor signals from at least two scattered light sensors and determining at least one further particle parameter from the previously determined average particle size and the scattered light sensor signals.
