1-9500nm High Performance nanoparticle size analyzer

 Details:

 BT-90 adopts dynamic light scattering theory. When laser beam irradiates nano particles, pulsate scattered light signals will be occurred. Rate-of-changes of signal intensity and frequency are related to motion state (speed and amplitude) of particles and motion state is related to particle size.

 

Hence, photomultiplier is used to receive these pulsate signals of scattered light, and these signals will be processed by digital correlator so as to recognize effective light scattering signals.

 

Through inversion processing of special software, particle size of particles in nanometer as well as its distribution will be calculated by Stokes-Einstein formula. The instrument can test wide distribution samples in nanometer, which has the characteristics of easy operation, high precision and wide test range, etc.

 

It applies to the fields of production, scientific research and teaching of nanometer materials.

 

 

Applications: 

Nano metallic oxide, Nano metallic powder, Nano ceramic material, protein, polymer latex, preparation of pharmaceutical, water/oil emulsion, paint, coating material, pigment, ink, toner, cosmetics and other fields of research, preparation and application of nano material, etc.

 

 

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.
