Main Features:

1. Advanced measurement principle: It carries out the principle of dynamic light scattering and photon correlation spectroscopy. Particle size is determined according to the Brown velocity of particle in the liquid.

Different sizes of particle, different velocity. When the laser irradiates these particles, particles of different sizes will make the scattered light speed fluctuation different. By Photon correlation spectroscopy, the particle size could be analysed according to photon fluctuation in specific direction.

2. High resolution: nano particle size is determined by PCS technology, which can distinguish nanosecond signal fluctuation. The core components of the instrument adopts CR256 digital correlator developed by our company, which is of high resolution to identify 8ns and of high signal processing speed.

3. High sensitivity and signal-to-noise ratio: It adopts the professional photomultiplier tube(PMT) of high performance, which is of high sensitivity and signal-to-noise ratio to photon signal.

4. Outstanding operational capability: We use high speed digital correlator CR256 for data acquisition and real-time correlation operation. The data processing speed is up to 162M so that it reflects dynamic light scattering information of particle in real-time and effectively.
