基于动态光散射法的双调节散射光接收系统设计
Design of Dual-modulated Scattered Light Receiving System Based on Dynamic Light Scattering
摘要
Abstract
The dynamic light scattering method is recommended by international ISO as the standard method for measuring the particle size of nanoparticles due to its non-contact,fast measurement speed and high accuracy.However,the traditional dynamic light scattering experiment has the problems of difficult adjustment,time-consuming and easy to introduce stray light,so the automatic adjustment function is introduced into the dynamic light scattering experiment,and a design scheme of dual-modulated scattered light receiving system is proposed based on the dynamic light scattering method.This solution uses a linkage sleeve to connect the sample cell and photodetector together,which effectively isolates environmental interference.At the same time,the coaxial characteristics are used to avoid the artificial adjustment error,and the scattering surface and the receiving surface are in the same plane,which greatly reduces the difficulty of experimental construction.The design optimizes the traditional dynamic light scattering experimental system,which is simple and solves the problems of difficult adjustment,and realizes the fully automatic and dual adjustment function of dynamic light scattering experiment,which is expected to provide a new technical means for light scattering experiment.关键词
