New Applications and Recent Developments of Particle Size Distribution Analyzer using the Laser Diffraction Technique
Author: Tetsuji YAMAGUTI; Manager; Scientific & Semiconductor Instruments; R&D Dept.; HORIBA, LTD.; Ph. D. – The LA-960 particle size distribution instrument which uses laser diffraction/scattering was released in 2013. This measurement method can analyze many particles simultaneously in a short period of time, without contact, with high precision and repeatability. The LA-960 has accessories for several types of samples such as concentrated slurries, i.e. CMP, water soluble powders such as pharmaceuticals, agglomerated powders such as magnetic materials and small volume samples. We will discuss the features of the instrument and accessories in detail. We will also provide actual measurement examples to illustrate the instrument performance. Recently, the LA-350 particle size distribution instrument featuring laser diffraction/scattering was also released. We will discuss the features of the instrument which include a reasonable size measurement range and high performance in a very compact product.
