LS-909 Laser Particle Size Analyzer

Details: 

LS-909 is an excellent dry & wet laser particle size analyzer based on customers’ demands for high-performance instrument. LS-909 adopts international advanced long-focus optical detection system, optimized double backward & reverse scattered light detector array, upgraded ADC signal acquisition system and innovative self-adaption noise suppression algorithm combined with imported high-quality He-Ne laser emitter, which can satisfy the demands for wider-distribution particles’ measurement with high automation degree, large dynamic range, good reproducibility and resolving power. This instrument owns intelligent measurement & control analysis software, specialized user-defined measurement report templates, as well as easy operation of report browsing, report contrast and data export. Main engine, dry & wet sample feeding system of LS-909

Applications: 

Measure the particle size distribution of samples have to be dispersed in liquid or of powders to be dispersed in gas. Theory: Light is an electromagnetic wave. When light meets with particles on it way of traveling, the interaction between light and particles will result in deviations of part of the light, which is called light scattering. The bigger the scattering angle is, the particle size will be smaller, the smaller the scattering angle is, the particle size will be bigger. The particle analyzer instruments will analyze the particle distribution according to this physical character of the light wave.
