Laser Particle Size Analyzer, Practical Series

The practical series laser particle size analyzer adopts the laser diffraction particle size measurement principle, combined with a highly sensitive annular photoelectric detector, significantly improving test precision. Its unconstrained free fitting technology truly reflects the particle size distribution, guaranteeing the authenticity and accuracy of test results. It is particularly suitable for testing materials with a narrow particle size distribution.

Features

User-Friendly Operation

Both manual and automatic modes are available for flexible selection based on sample characteristics. In specific scenarios (e.g., samples with unknown properties or tests requiring special parameters), users can first conduct a preliminary test in manual mode. After clarifying the sample features and optimal test conditions, formal testing can be performed in automatic mode for efficiency.

Rapid Measurement

Wet dispersion: When set to automatic mode, all operational procedures are executed automatically, including automatic water supply, ultrasonic sample dispersion, stirring, circulation, background calibration, sample testing, data analysis, drainage and cleaning. This dramatically shortens the measurement cycle, with the entire process taking less than 2 minutes.

Dry dispersion: The intelligent operation system supports one-key testing: simply place the sample into the instrument, and all subsequent processes—including dust collection, air supply, and feeding—are executed automatically. This not only reduces the testing workload but also eliminates errors caused by human factors, further enhancing the accuracy and authenticity of test results.

Advanced Optical Path Design

The converging light Fourier transform technology frees scattered light at large scattering angles from the constraints of the Fourier lens aperture. The reduced focal length enhances the instrument’s resolution, while the annular multi-element silicon photodiode ensures the collection of all particle light signals, greatly improving measurement resolution.

Automatic Optical Path Alignment System

The automatic alignment system for optical components is equipped with four hybrid stepping motors, with a micro-precision of 0.1μm. This ensures the instrument’s optical path always maintains optimal performance, eliminating the troubles and difficulties of manual optical path adjustment and further enhancing the accuracy and stability of test results.

Practical Sample Dispersion System

Wet dispersion system: The fully built-in wet sample dispersion system integrates mechanical stirring, ultrasonic dispersion and circulation. This guarantees the uniform dispersion and distribution of particles, avoiding issues like uneven particle distribution and sedimentation of large particles caused by long pipelines in external dispersion systems, thus ensuring the representativeness of test results.

Dry dispersion system: The turbulent dispersion technology and normal shock shearing effect achieve thorough particle dispersion, ensuring reliable test performance.

Software

The original unconstrained free-fitting technology collects scattering data during the measurement process. It frees particle analysis from the constraints of fixed functional models, truly reflecting the particle size distribution.
