The Microtrac S3500 is a industry-preferred Laser Diffraction (LD) analyzer, ideally suited for various particle characterization tasks. It is the first particle size analyzer that uses three precisely placed red laser diodes to accurately characterize particles like never before.
The patented Tri-Laser System provides accurate, reliable and repeatable particle size analysis for a diverse range of applications by utilizing the proven theory of Mie compensation for spherical particles and the proprietary principle of Modified Mie calculations for non-spherical particles. The S3500 measures particle size from 0.02 to 2,800 µm.

Product Overview
10 Most Common Errors in Particle Analysis - And How to Avoid Them
Particle analysis is an integral part of the quality control of bulk materials and is routinely performed in numerous laboratories. The methods used have often been established for years and are hardly ever questioned. Nevertheless, the procedure should be critically reviewed from time to time because a whole series of sources of error can negatively influence the results of a particle analysis. This white paper is intended to provide food for thought to make methods for particle characterization more reliable and accurate.

Accuracy and Precision of Microtrac Particle Analyzers
Accuracy and precision have distinct meanings. Generally, accuracy refers to the ability of an analytical device to provide a measurement that is within a defined error from an established, true, and verifiable value. Precision is a measure of the recurrence of a value whether it is accurate or not. Two types of precision can be described: repeatability and reproducibility. In terms of particle size measurement, repeatability refers to the ability of an instrument to repeat its own measurement while the same sample resides in the circulating system. Reproducibility, on the other hand, is related to the comparison of two or more instruments in which representative (repeatable sampling assumed) samples are introduced to each of the instruments. Repeatability is statistically more variation-free than reproducibility because a single instrument measures the same recirculating sample.
