A Guide to Choosing a Particle Sizer

The choice of a particle size analyzer has never been more difficult. There are several techniques from which to choose and variations within each technique. Sales literature claims of specification and performance have become highly inflated, confusing the first-time buyer; the result has been to hinder and not help the decision making process. Many particle sizing instruments were originally designed to address specific problems. Although some have found additional uses, there is still some truth to the notion that certain techniques are best suited for particular tasks. The idea that one instrument will suit every particle sizing need, and hence solve all problems, is not supported in practice.
