입자의 크기 측정은 입자의 물리적 상태인 결정구조와 결합상태에 다른 입자의 굴절률과 흡수율과 회절 상태 등을 이용하여 입자의 크기를 0.02 ~ 2,000um 까지 측정하는 장비
입자크기 측정
1. Method : Laser diffraction using Fraunhofer and Mie scattering theory including back scattering
2. Measuring range
가. 0.02 to 2000 microns in a single range
나. This system does integrate back scattering into its optical system and measure up to 0.02microns
3. Resolution : Results reported in 100size classes
4. Measuring sample : Emulsions, suspensions, dry powders
5. Sampling method
가. Powders in liquid suspension
나. Emulsion measurement : Emulsion can be used to suspend powders for analysis
6. Single sample dispersant unit :
가. Incorporating variable power ultrasonic dispersion and mechanical stirrer and recirculation pump with independently variable speed
