Described is an improved method for measuring the particle size of ultrasmall particles (111) which are suspended in a fluid. Laser light (121) is scattered by the particles, and the scattered light (122) is received by a light detector (131) which provides an electrical measuring signal (Sm) which is representative of the intensity of the...

Described is a method for measuring the particle size of ultra-small particles (202) which are suspended in a fluid. Laser light (121, 123) is guided via a first optical path (160) to a suspension (201), and light (125) scattered by the particles (202) in the suspension (201) is guided to an optical detector (140) via a second optical path (170)...
