Abstract
Knowledge of particle size distributions in various fields of research, industry, and medicine is continually increasing in Importance. To cope with the requirements, many sophisticated methods have been investigated and implemented as measuring systems. References 1-4 are a sample of recent publications on the subject, and they include citations for more basic material. Each of the particle diagnostic methods practiced today has its advantages and drawbacks. As advantages one may count accuracy, speed of data acquisition, wide dynamic range, and simplicity of operation. These advantages almost never come together in the same instrument. Limiting ourselves to noncontact optical measurements, one can state that simplicity is not commonplace, while reliability is often questionable.4 One main cause of the difficulties with the existing measuring Systems is that the measured parameter (scattered light distribution, Brownian motion, velocity, absorbed electrical charge, etc.) is related to particle size but is not a direct measurement of the particle itself.
