Introduction
Angstrom Advanced ABT-9000 dynamic light scattering nano laser particle size analyzer is a project which Angstrom Advanced introduced research results and carries out with them together. The principle is when nano particles are scattered in medium, because of Brownian Motion of liquid molecular, nano particles are impacted and doing irregular movement, the smaller the particle is, the faster the movement is, so the range is bigger; the bigger the particle is, the slower the movement is, so the range is smaller. When nano particles are illuminated by laser beams, the pulsatile signals of scattered light will be generated, the change rate of optical signal’s intensity has some connection with particles’ motion state (speed and range), that is, has some connection with particle diameter, photomultiplier receives these pulsatile signals of scattered light, transform them into electric signals, and process by digital correlator, identify validated dynamic light scattering signals, and then use inversion processing of software, equation of Stokes-Einstein, calculate the nano particle diameter and its particle size distribution.
Features
- High accuracy and repeatability: the error of accuracy and repeatability are much less than the allowable error through testing Standard Sample. The error of accuracy and repeatability are all less than 3%, other indexes are up to the International Standard ISO 13321
- Fast testing: just spend less than 5 minutes testing sample and getting an accurate result
- A precise temperature control system: temperature control precision of 0.2°C,to ensure accuracy of test
- High precision photomultiplier (PMT): imported photomultiplier (PMT), high sensitivity, high-speed, stable performance, precise recognition of each photon
- High performance photon correlator: adopt photon correlator which developed by large scale integrated circuit(DSP), multichannel, high-speed, identify photon signal of different particle size effectively
- Functional software: user-friendly interface makes operation easily, animation display. The software also has multi-language function, 17 languages switch easily; convert test report into the format of Excel, Word, etc; also the software integrates a test report edit function
