WD-2309B Particle Size Analyzer for Wet and Dry Samples Technical Advantages

1. Wet and dry, unique separated dispersion module.

This instrument integrated wet and dry dispersion test in one, successfully resolved the problem of dry and wet technology integration, realize one key to switch.

2. Intelligent fully automatic and manual operation modes can be freely switched

With intelligent automatic mode of operation, to achieve a key test, click the "test", all process will be completed automatically, not only reduce the testing workload, but also eliminate the interference of human factors, to further improve the accuracy and authenticity of testing results.

Wet method: a key to complete water-supply, ultrasonic dispersion, circulation, testing, cleaning, data record, data analysis, save and print are automatically completed, only take 2 mins.

Dry method: a key to complete the dust collecting, compressed air supply, feeding, testing (the patented technology of turbulence dispersion and the sample window of the negative pressure device make the sample be fully dispersed), data processing and other operation, take 1 min.

3. Trusted optical path system

Using the patented technology of Fourier transform of convergent light, the large-angle scattered light is not limited by the aperture of the Fourier lens, the focal length is shortened to the shortest, and the dual laser orthogonal light use auxiliary semiconductor laser to expand the measurement range by enlarge scattering angle from 45 degrees to 135 degrees. The resolution capability of the instrument is effectively improved, and the measurement range can be changed without changing the lens. Sealed optical path, good dust-proof performance.

4. Automatic optical path alignment system

With four hybrid stepping motors in the optical components, precision can be 0.1um, ensure the instrument light path is at its best performance, enhanced the accuracy and stability of test results.

5. Embedded fully auto sample dispersion system

Auto wet dispersion system can realize one-key operation, be designed mechanical stirring, ultrasonic dispersion, and circulation path as one. It ensures particles uniform dispersion and distribution, avoids many bad phenomena, such as uneven distribution of particles, large particles deposit because of the long outer dispersing system tube, and it guarantees the meaningful of test result

For dry dispersion system, turbulence dispersion patented technology and normal shock shearing effect make particles sufficient dispersion, can test powders range from 0.1 micron to 2800 micron.

6. Instrument software

Original unconstrained free fitting technology collects scattering data during the measurement process, it has the ability to automatically resolve multi-modal particle groups, and is not restricted by any functions. The analysis results completely depend on the distribution of the scattering spectrum, which maximizes the fitting accuracy and truly reflects the particle size distribution status of all samples. 

Particles below 2µm are tested in twelve particle size classes with extremely high physical resolution. Ordinary inversion software testing adopts function simulation calculation, not real measurement value, so the test performance of its instrument is greatly reduced.
