SUMMARY Microscopic size analysis is the most direct of all size analysis procedures and is frequently used as a calibration technique for other methods. The commonly used microscopic procedures, however, are laborious and the results are frequently inaccurate because of the small number of particles measured by most investigators. Using the Vickers Eyepiece, we have built an inexpensive (> $ 1,000), semiautomatic microscopic size analyzer with which particles are sized, sorted into sixteen classes, and counted, accurately and quickly. The instrument combines direct observation with speed, accuracy, and ease of measurement to make it a valuable tool for the size analysis of a wide range of materials.
