WJL-622 Dry and Wet Laser Particle Size Analyzer, 0.1～600 Microns (Wet Method), 0.1～600 Microns (Dry Method), Shanghai INESA Physico-Optical Instrument CompanyLimited (CAT#: STEM-AIAE-3232-LGZ)

The dry-wet dual-purpose laser particle size analyzer adopts the full-scale Mie scattering theory, fully considering the optical properties such as the refractive index of the measured particle and the dispersion medium, and inverts the particle group according to the change of the scattered light intensity of the particles of different sizes at various angles. The particle size distribution data is in line with the relevant requirements of ISO13320.

1. Dry dispersion: In the dry state, the sample is uniformly transported into the high-pressure airflow through the automatic dry powder sampler, and is sprayed into the disperser at a high speed under the drive of the high-pressure airflow, and the sample has been fully dispersed when it reaches the outlet of the disperser. , the laser beam enters the collector after passing through the sample, and the computer immediately displays the particle size distribution.
2. Dry dispersion without any dispersant and solvent.
3. It adopts silent oil-free air compressor and high-efficiency condenser to ensure the production of pure compressed air.
4. Instantaneous dispersion, instant measurement, fast test speed and high analysis efficiency, completed within one minute from sample injection to result output.
5. Wet dispersion: WJL series dry and wet dual-purpose laser particle size analyzer dispersion system can fully disperse the tested sample. Ultrasonic time, stirring speed and circulation speed can be set according to the difficulty of sample dispersion. Good shielding treatment enables ultrasonic dispersion and sample testing to be carried out at the same time. High-power ultrasonicator (100W) can fully dispersion to obtain true particle size distribution data.
6. Test data: data averaging, statistics, comparison and mode conversion can be processed, with differential distribution, cumulative distribution, standard classification, R-R distribution, custom classification, classification by mesh and other formats, with single peak, Multiple modes including bimodal, multimodal and mixed peaks.
