Research on Particle Size Measurement of Chinese Medicine Powder by Laser Particle Size Analyser
The particle size and particle size distribution, which are related to the quality of the products and the safety of the drugs, are the important physical properties of the Chinese medicine powder. However, because of the irregularity and inhomogeneity of particle size, the results obtained by different measurement methods are different. Laser particle size measurement has been widely used in the determination of traditional Chinese medicine by its fast operation, wide measuring range, and good reproducibility. This paper focused on the principles and characteristics of laser particle size measurement and its application of Chinese medicine powder.
