Features:

1.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 accord with the International Standard ISO 13321.
2.Fast testing: a reliable test result can be obtained in less than 5 minutes.
3.Precise temperature control system: temperature control precision of 0.2°C,to ensure accuracy of test results.
4.High precision photomultiplier (PMT): high quality photomultiplier (PMT), high sensitivity, high-speed, stable performance, precisely identify each photon.
5.High performance photon correlator: adopted photon correlator which developed by large scale integrated circuit (DSP), multichannel, high-speed, identify photon signal of different particle size effectively.
6.Powerful software system: user-friendly interface makes easy operation, animation display. The software also has multi-language function, 17 languages can be switched easily; freely convert test report into the format of Excel, Word, drawing, etc; also the software integrates edit function for test report, provides 12 formats in Chinese and English for users to choose at any time.

Good accuracy:
1. Reasons for good accuracy:
a. Laser, detector and signal transmission system are stable and reliable.
b. Has precision temperature control system: precision of temperature control can reach 0.5°C to ensure that test result is accurate and reliable.
c. High precision photomultiplier (PMT): adopts imported PMT of small dark base, high sensitivity, fast speed and stable performance, could recognize each photon precisely.
d. High-performance photon correlator: adopts photon correlator invented by large scale integrated circuit(DSP) which has more channels and fast speed, can recognize photon signals produced by particles of all kinds of particle size effectively.
2. Examples for accuracy verification
a. Test result for 100nm standard sample is 101nm, and error range is 1%, much lower than 10% which is allowable range required by International Standard ISO13321.
b. Test result for 27.33nm standard sample is 27.57 nm and error range is 0.87%. Test result for 62.11nm standard sample is 61.55nm and error range is 0.9%. Both of them are much lower than 10% which is allowable range required by international standard ISO13321.
c. Compare with test results of overseas advanced nanoparticle size analyzer: Good consistency.
