Rise-2012 dry laser particle size analyzerWorking Principle:

The Rise-2012 dry laser particle size analyzer adopts the full range Mie scattering theory, fully considering the optical properties such as refractive index of the measured particles and dispersed media. Based on the changes in scattering intensity of particles of different sizes at various angles, the particle size distribution data of the particle group is inverted.

The data calculation of particle testing is generally divided into two methods: unconstrained fitting inversion and constrained fitting inversion. Constrained fitting inversion assumes that the particle population follows a certain distribution pattern before calculation, and then uses this pattern to invert the particle size distribution. This type of operation is relatively simple, but due to the inevitable deviation between the assumptions made in advance and the actual situation, the test data obtained by constrained fitting cannot truly reflect the actual particle size distribution of the particle group.

Unconstrained fitting inversion means that no assumptions are made about the particle population before testing, and the particle size distribution of the particle population is accurately calculated directly through light intensity. This calculation is based on reasonable detector design and granularity grading, which puts high demands on the equipment itself. The Rise-2012 dry laser particle size analyzer adopts a non-uniform cross three-dimensional fan-shaped matrix detector array and reasonable particle size grading, which can accurately measure the particle size distribution of particle groups.

Rise-2012 typeTechnical features:

Testing a stable foundationOnly when the system can provide stable optical signals can the stability of test data be fully guaranteed. The Rise-2012 dry laser particle size analyzer uses a He Ne gas laser light source with a wavelength of 0.6328 microns, short wavelength, narrow linewidth, good stability, and a service life of over 25000 hours, which can provide stable laser source signals for the system.

Guarantee of Reliable DataTo ensure the reliability of test data, the first step is to design the signal detection system reasonably. The quality of the dispersion effect of the tested sample is another decisive factor in obtaining the true results.

detectorThe photoelectric detection system design is highly sensitive, with one main detector and multiple auxiliary detectors arranged in a non-uniform cross three-dimensional fan-shaped matrix. The maximum detection angle reaches 90 degrees, fully ensuring the comprehensiveness of signal detection.

optical pathAdopting a range design, converging light path * reduces the Fourier lens group, making the measurement range wider, resolution higher, and light path adjustable.

Powerful analysis software：

The PADMAS Particle Diameter Measure&Analysis System has powerful functions, and test data can be processed through averaging, statistics, comparison, and pattern conversion. It has various formats such as differential distribution, cumulative distribution, standard grading, R-R distribution, custom grading, target grading, and quantity distribution. The default grading is 130 levels within the range of 0.02~2000 microns, and the grading can be customized within the range of 1~130 levels. The test report includes particle size distribution graphs and particle size data charts, as well as characteristic parameters such as D10, D50, D90, average particle size, and specific surface area. There are four custom parameters that can be entered as needed, and weight specific surface area and volume specific surface area can be interchanged. Granular data can be saved to EXCEL. Supports printing test reports in both Chinese and English formats. The header and footer can be modified as needed, and there is a print preview function. It can save granularity distribution graphics and granularity data charts in image or PDF format for interactive use with WORD. Other processing functions can be added according to user needs. Easy to operate: Standard, quantitative, and simple operations can be mastered proficiently in a short period of time, and the testing data process can be completed within 1 minute.

Dispersion method

The Rise-2012 dry laser particle size analyzer is a high-performance instrument. The system consists of a laser particle size analyzer, an automatic dry dispersion system, an oil-free air compressor, an efficient condenser, and other components. In the dry state, the sample is uniformly transported to the high-pressure airflow through an automatic dry powder sampler, and continuously sprayed at high speed into the disperser under the drive of the high-pressure airflow. At the outlet of the disperser, the sample has been fully dispersed, and after passing through the laser beam, it enters the collector. At the same time, the computer immediately displays the particle size distribution information.
