Laser Particle Size Analyzer LLPA-A21

Labtron’s Laser Particle Size Analyzer LLPA-A21 applies the Mie scattering principle, which analyzes how laser light is scattered by particles based on their size and optical properties. A laser beam passes through the dispersed sample, and scattered light is detected at different angles. Using this data, the system calculates the particle size distribution with high precision. Mie scattering is ideal for a wide range of particle sizes and materials, making it more accurate than basic diffraction methods, especially in industries that demand tight particle control like pharmaceuticals and advanced materials.

The converging Fourier transform optical path allows the Laser Particle Size Analyzer LLPA-A21 to capture scattered light efficiently without requiring a long optical bench. This optical configuration maintains high measurement resolution in a compact system, enabling precise detection of particle size distribution over a wide range. It also ensures optical stability, which is crucial for repeated testing and long-term use in research and production environments.

Our Laser Particle Size Analyzer LLPA-A21 features a sealed wet circulation system with a micro-circulation design that avoids dead zones and eliminates residual liquid. An integrated ultrasonic disperser (40 kHz, 100 W) ensures thorough mixing and prevents particle agglomeration. This setup is essential for accurate measurement of powders, emulsions, or viscous suspensions, as it ensures each test begins with a uniformly dispersed sample.

The Laser Particle Size Analyzer LLPA-A21 includes intelligent one-touch operation, automatic optical path calibration on both X and Y axes, and a misoperation protection function. It also features a fogging detection system that maintains optical clarity. These features simplify operation, reduce user error, and allow even non-specialists to perform consistent tests safely and accurately.
