PA2000LWE intelligent laser particle size analyzer, perform auto test, auto alignment, auto water supply, auto drainage, auto bubble removing, auto ultrasonic dispersion, auto cleaning etc., really realize one-key operation. It adopt full built-in sampling system, effectively prevents large particles sedimentation problems in the circulation pipeline, ensure good accuracy. It adopts comprehensive Laser diffraction particle size measurement principle with highly sensitive ring photoelectric detector improving the test accuracy greatly, Original designed unconstrained free fitting software technology, a true reflection of the particle size distribution, to ensure truth and accuracy of the test results. Therefore especially suits the laboratories of enterprises, colleges and universities and research institutes to use.
Main Features
- Advanced design of light 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.
- Built-in dispersion units:
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.
- 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.
- 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.
- 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.
- 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 test measurement in the manual mode first, and after having an idea of the sample features and the measurement conditions, measure the samples in the automatic mode.
- 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.
- Quick measurements:
set “ automatic” mode, all operation procedures are performed automatically,automatic water supply, automatic ultrasonic sample, stirring, circulation,background testing, sample testing,analysis , draining and cleaning, which significantly reduces the time for measurements, the full process only take 2 minutes.
- Data analysis
Errors in the data are rejected and the measurement results are automatically processed. Manual data processing is not necessary and the output is more standard.
