Overview
AS-2012 Laser Particle Size Analyzer is a latest laser particle size analyzer with extended minimum size range 0.04 micrometer. The major detector array consists of 71 photocells with maximum detecting angle 21.5°. Crossly positioned irregular side and back array comprises 9 photocells with maximum angle 135°. Optimized reverse Furier optical design and unique integration of light path and optical bench contribute to stable light path; moreover it reduces light path adjustment to zero. Thanks to advanced mechanical design and processing technique the unit becomes more compact; streamlined cover makes for easy operation and maintenance; effective shielding and disturbance-resistance technology contributes to the electric stability, accurate result and repeatability.

Tehnologies
●AS-20 dispersing unit features internal ultrasonic, circulation, agitation and timed ultrasonic. The peristaltic pump prevents the suspension from being contaminated during circulation to secure the accuracy of the test results. AS-20 can work with small volume cell or flowthrough sample cell. The former caters to organic medium and the later to water whereas the transfer between both is user-friendly.●AS-2012 is a high-tech instrument incorporating technologies of optic, mechanic, electric and computer. The acquired data is processed by special analysis system and result printed out by printer. ●Optimized reverse Furier optical design and unique integration of light path and optical bench contribute to stable light path; moreover it reduces light path adjustment to zero. Thanks to advanced mechanical design and processing technique the unit becomes more compact; streamlined cover makes for easy operation and maintenance; effective shielding and disturbance-resistance technology contributes to the electric stability. ●Innovative photocell array improve the resolution of the unit. The major detector array consists of 71 photocells with maximum detecting angle 21.5°. Crossly positioned irregular side and back array comprises 9 photocells with maximum angle 135° extends the minimum size range to 0.04 micrometer.●The semiconductor laser waved 635nm and powered 3mw works for more than 25000 hours therefore extends the running life and stock life of the particle size analyzer.●AS-2012 works with advanced Mie scattering theory and excellent H.Golub inversion algorism. With the ideal combination of software and hardware, the test is always fast and accurate for whatever unimodal or multimodal distribution.●Flexible output makes it editable for the data and curve of accumulative distribution, data and histogram of differential distribution and typical values according to specific requirement.●AS-2012 completely meets the requirement of ISO13320-1, an international norm on laser particle size analyzer and each unit goes through strict quality control with national reference material.
