 as they are circulated between the flow cell, which is placed in the
 measurement unit, and a dispersion bath in the sampler.  Measurement is possible by simply holding the high-concentration sample particles to be measured between two glass slides.
 The dispersion bath incorporates a stirrer and an ultrasonic sonicator.   Samples for which the particle size distribution would be changed by dilution can be measured in their original state, or with the minimum required
