WET-2000ZDE Laser Diffraction Particle Size Analyzer Features

1. Advanced design of optical path

A patented technique of Fourier transform of converging light released the scattered light at large-scattering-angles from the restriction of the aperture of the Fourier lens. The focal length is reduced to enhance the resolution of the instrument, and ring shaped of multi-element silicon photo-diode ensure gathering all the light signals of particles, highly improve the resolution.

2. Built-in automatic wet dispersion unit

We carefully aligned the stirring set-up, the ultrasonic dispersing unit and the sample circulation pipes, and fixed them inside the instrument. Such a built-in design effectively prevents the inhomogeneous dispersion and sedimentation of big particles, which can be observed in the designs that these dispersing units are separated from the instruments, where the sample circulation pipes are therefore too long, the sample will be sufficiently dispersed.

3. Unconstrained fitting techniques

The particle analysis software uses a unique unconstrained data fitting technique that we developed to obtain data of real particle size distribution; this is particularly important for researchers.

4. Micro sample chamber (optional)

The capacity of the sample chamber is as small as only 10ml. This helps with measuring expensive/precious samples, or samples difficult to be dispersed within medium.

5. Modern measurement control (intelligent SOP operation)

Users can perform all measurement procedures by simply operating on the PC and have ideal results in a very short time.

6. User-friendly operation

manual mode and the automatic mode, freely choose, to measure according to the sample features. In some conditions (e.g. the sample have unknown features or there are special requirements for the measurements), users can make a trail measurement in the manual mode first, and after having an idea of the sample features and the measurement conditions, then measure the samples in the automatic mode.

7. Fully automatic light path alignment

A precise four phase hybrid stepping motor automatically aligns the optical path and can adjust it at any moment, precision is up to 0.1um. This releases users from manual adjusting the optical path and improved accuracy and stability of the measurement results.

8. Quick measurements

Under automatic mode, all operation procedures are performed automatically, automatic water supply, automatic ultrasonic sample, stirring, circulation, background testing, sample testing, draining, and cleaning, can significantly reduce the measurement time, the whole procedures only take around 2 minutes.

9. Data analysis

Errors in the data are rejected and the measurement results are automatically processed. Manual data processing is not required, can output accredited data.
