Stream Counters Using Optical Inspection Procedures

The use of ultrasonic measurements to study submicron particles has been reported by Scott, et al. [26] 

4 Stream Counters Using Optical Inspection Procedures 

The HIAC Royco Instrument Corporation manufactures a whole range of photozone stream counters [34, 35]. The optical system used in the different instruments depends on the information requirements of the particular study. For example, 

The Climet stream counter, shown in F te 6.10, characterizes the fineparticles by collecting and measuring most of the forward scattered light and a high proportion of the back-scattered light with the aid of an elliptical mirror [39]. The interro-
