Willemse, A.W. (author), Merkus, H.G. (author)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)...patent 1998

Marijnissen, J.C.M. (author), Willemse, A.W. (author), Roos, R.A. (author)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...patent 1997
