Horiba has developed the new LA-300, a compact particle size distribution analyzer for industrial applications. The instrument features the superior accuracy and reliability of the highly-regarded LA series of analyzers. This high-performance, versatile instrument can accurately measure particle sizes in a range of 0.1 to 600 microns. This paper describes the rationale for creating a compact, cost-efficient analyzer and provides an example of the analyzer’s measurement performance.
As the needs for particle-size distribution analysis increase, there are various requests for sophisticated particle-size distribution analyzers for measuring broader range of particle size distribution, and for more useful built-in functions. In response to these demands, Horiba has produced the Laser Scattering Particle-Size Distribution Analyzer LA Series. In addition there exists the demand for smaller, inexpensive particle-size distribution analyzers that retain the superior features of the more sophisticated laser scattering particle-size distribution analyzers. These features include rapid measurement capability; good, repeatable accuracy; and ease of use to eliminate operator bias. To meet these requirements, Horiba introduced the LA-300; a compactlydesigned laser scattering particle-size distribution analyzer that has a remarkably small footprint.
