AELAB Laser Particle Size Analyzer WJL-602 Series – Precision Particle Sizing

A laser particle size analyzer measures the size distribution of particles in a sample using laser diffraction technology. It provides rapid, accurate analysis of particle sizes ranging from nanometers to millimeters. This instrument is essential in industries such as pharmaceuticals, chemicals, mining, and food, where particle size affects product performance and quality. The analyzer works by passing a laser beam through a dispersed sample and measuring the angle and intensity of the scattered light. The data is then processed to determine particle size distribution.

Features:

• Work principle: The laser particle size analyzer is based on full measuring range of Mie scattering theory, sufficiently considering the optics nature such as sample and decentralized medium refraction coefficient and so on. On the basis of laser illuminate size and the size distribution regular pattern of scattering light energy that comes from the sample inversely calculate out sample group.
• Technique feature: The laser particle size analyzer work principle is well-developed, hardware design is very reasonable, the product is designed according to the international engineering standard ISO-13320, GMP Regulation and FDA/21CFR 11 absorbs England, America, Germany and other countries well-developed experience on the size analysis, all features of the product are domesticly and leading.
• Illuminant: The laser particle size analyzer adopts He-Ne’s laser make illuminant, the wavelength is 0.6328 micron, wavelength is short, string breadth is narrow, stability is good, and laser power source and laser tube service life is more than 25000 hours.
• Light electricity probe: The laser particle size analyzer light electricity system is designed uniquely. The primary detector is one, many assist detectors presenting non-uniform intercourse and three dimension fan-shaped ranges matrix rank. The largest test examination horn angle attainability is up to 135°
• Light route: The laser particle size analyzer adopts a measuring range designed, the convergent light route is unique, decreasing Fourier lens, as a result the measurement range broader, the resolution is higher, the error is minimal.

🔬 How It Works?

The analyzer operates on laser diffraction and Mie scattering theory. A He-Ne laser beam passes through a dispersed particle sample (wet or dry), and detectors capture the scattered light across a wide angular range. Using advanced algorithms, the instrument calculates particle size distribution with high precision. The optimized optical pathway ensures broad measurement range, minimal error, and high repeatability.
