Analytical Test of Particle Size of Traditional Chinese Medicinal Micropowder
The common determination methods of partical size of traditional Chinese medicinal micropowder were expounded briefly. The advantages and disadvantages of every testing methods were analyzed ,and laser diffraction method was narrated in detail. The particle sizes and particle size distributions of Banqing micropowder ,Huangqi-micropowder and Siweichuanxinliansan micropowders were tested by Mastersizer 3000 laser particle analyzer. Dry laser diffraction method is thought to be the most suitable to particle size testing of Chinese medicinal micropowders.
