ABSTRACT:
A method of evaluating a scattered light signal generated by a scattered light receiver when detecting especially fine particles in a carrier medium, wherein the scattered light signal runs through a filter algorithm operation to evaluate the scattered light signal subject to specific filter algorithms, the filter algorithm operation being based on a slope of the scattered light signal.
