Study of Liquid Single Particle Size Detection Based on Lateral Scattering Technique

Abstract:

A new type detecting device was developed according to the demand of the liquid single particle size analysis. Based on side scatter detection technology, the device used a semiconductor laser as light source. By introduction of the hydrodynamics, sample particles were focused sequentially through the measuring beam. The lateral scattering lights were received by high-sensitivity avalanche photodiode. So the particles’ size can be achieved by analyzing the scattered light pulse signal magnitude. Experiment results showed that the device can detect 0.35μm particle effectively, and its particle size detection limit is superior to the existing liquid particle detection products in the market. In addition, the hydrodynamics focusing technology contributed to more prominently distinguish rate. The device has broad application prospects in the pharmaceutical, medical and polymer industries.
