Apparatus and method for measuring a particle size distribution on the basis of a light scattering method

摘要

Device for measuring a particle size distribution on the basis of light scattering,– in the case of a sample (8) with from a light source (1) could be irradiated light originating is,– in the case of which the scattered light produced by a photodetector (10) can be detected and– in the case of the particle size distribution on the basis of a by the photodetector (10) detected scattered light - intensity pattern can be determined,– in the case of a tracking mechanism (22, 23, 27, 30, 31, 32, 35) is provided, by means of which an optical axis of the light source (1) and / or an optical axis of an optical device (6, 9, 26, 33, 34) between the light source (1) and the photodetector (10) with an optical axis of the photodetector (10) can be brought into coincidence,– in the case of a device for measuring a quantity of light of the sample (8) on the incident light is provided,– in the case of a device for measuring a to the photodetector (10) incident light quantity is provided, wherein the optical axes..
