Auto Sampling Dry Dispersion Laser Particle Size Analyzer

PA-CIIALD Dry Dispersion Laser Particle Size Analyzer uses compressed air to disperse the sample, suits for the measurement of samples that can’t be dispersed in liquid.

Applications
measure samples that have chemical and physical changes when dispersed in water.

Principle
Uses the principle of laser light scattering to determine particle size distribution. Our instruments own the advantages of wide measurement range, good repeatability, simple operation and etc. through our system integration and optimization for optics, mechanics, electronics and computer.

Report Items
Particle size distribution table, particle size distribution curve, median diameter, Characteristic particle size, width coefficient, SSA, industrial segmented percentage of particles, > 80μm percentage (fineness), other synthesis parameters of particle size , etc.

Features

• Adopt unique scattered light detection around a sphere surface (patent no.:95223756.3), after lens (also known as “reversal” or “converging light”) Fourier transform structure, place large angle detectors on proper spherical surface, to realize the accurate focusing of large angle scattered light.
• Use integrative laser emitter (patent no.: 00228952.0), effectively reduce the thermal deformation of laser tube, the influence of outside mechanical vibration on the stability of the instrument.
• Measurement window material uses high quality optical materials, window components adopt full stainless steel material, wear-resisting, easy to clean, and maintenance is convenient.
• Light path system uses fully-enclosed design, preventing dust pollution and outside light pollution.
• Dry dispersion avoids the physical or chemical changes of the samples in liquid. Testing process will not consume dispersion medium and dispersant, save money and help to protect environment.
• Vibration motor of dry sample feeder system is adjustable, to realize effective control of beam obstructions
• Fitness, specific surface area, R-parameters and percentage composition of fixed particle size specially designed for the cement industry.
