Intelligent Full-automatic Wide Distribution Wet Laser Particle Size Analyzers

Order Id: PSA2005B
Categories: Particle Size Analyzers 

 

 

PSA2005 is an intelligent and automatic laser particle size analyzer with a wide measurement range of from 0.05–780um. The size distribution is determined by measuring the intensity of the scattered light as a function of the scattering angles, and the theoretical base of calculating is the Mie light scattering. It combines together a patented technique of Fourier transform of converging light, the design of perpendicular light paths, an unconstrained data fitting program and intelligent measurements. All these guarantee the precision of the results throughout the wide measurement range.

 

 

 

 

Main Features
 Principle: Particles of different sizes scatters the illuminating laser into different patterns. In this instrument He-Ne laser is used to illuminate and photon detector arrays measure the forward, sideward and backward scattered laser. Software automatically converts the patterns into size distributions.
 Novel technique: It uses a patented technique of Fourier transform of converging light and the design of perpendicular light paths. Photon detector arrays measure the forward, sideward and backward scattered laser. This ensures the precision and reproducibility of the measurement results obtained from nano-particles.
 Intelligent measurements: Users only need to add in their samples, and click the ‘automatically measure’, and then all the procedures, including pumping in water, dispersing, circulation, measuring, cleaning, data recording, analyzing, saving and printing etc. are automatically executed. This reduces users’ workload, as well as minimizes any possible errors resulted from manual operations.
 Built-in dispersing system: 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.
 Unconstrained data fitting program: the particle analysis software uses a unique unconstrained data fitting technique that we developed to intelligently measure an unknown size distribution, this is particularly important for material researchers, or for measuring particle size distributions with multiple peaks in data.
 Automatic alignment: A precise four phase hybrid stepping motor automatically aligns the optical path and can adjust it at any moment. This releases users from manual adjusting the optical path and improved accuracy and stability of the measurement results.
 Micro sample chamber: The capacity of the micro sample chamber is as small as only 10ml. This helps with measuring expensive/precious samples, or samples difficult to be dispersed within medium.
 Rich software functions: Beside the basic function of analyzing the size distributions, the software also has the following features:
 The output has rich content including: size distribution, R-R distribution, logarithmic distribution, statistics within different size ranges, volume distribution, number distribution, the percentage of particles of a certain size, or a certain size range, and comparison of multiple results.
 The output could be in Word, Excel, Bmp pictures and Text formats, and this makes easy viewing and referencing the results at different situations.
 It supports English and Chinese languages, and it can be changed to many other language versions according to the user’s needs.
 Calibration: Throughout the measurable size ranges the instrument is calibrated with China’s standard reference particulate materials. The resolution and accuracy are guaranteed.
