Title: Appts. for concn. measurement in turbid solns. - contg. more than one type of particle, using scattered light measurements
Inventor: TOMISHIMA AKIRA
IPC: G01N21/53
Filed: 1975-06-28
Abstract: The soln. is illuminated by a light source and the appts. which has two photoelectric converters, measures the scattered light from a point in the same plane as the axis of the incident light. The measurements are taken from two separate points at an angle to one another w.r.t. the optical axis. Because of the different properties of the suspended particles, the form of the scattered light from the point of measurement is different in different directions. The differing amts. of scattered light received by the photoelectric converters can thus be used to measure the concn of particles in the liq. having special properties. Accurate measurement of the concn. of particles of one type in the soln. in the presence of other particles can be made either intermittently or continuously.
