Laser diffraciton principle of laser particle size analyzer

图片
          Laser Diffraction, also known as Static Light Scattering, has become one of the most widely used particle sizing distribution  techniques across various industries.  Samples can be analyzed on either a liquid suspension or dry dispersion basis.  The sample  material is passed through a laser beam which results in the laser light scattered at a wide range of angles.  Detectors placed at  fixed angles measure the intensity of light scattered at that position.  A mathematical model (Mie or Fraunhoffer Theory) is then  applied to generate a particle size distribution. The final result is reported on an Equivalent Spherical Diameter Volume basis. static light scattering application in the laser particle size analyzer Particle Size by Laser Diffraction is widely recognized by numerous standards and guidance agencies such as the ISO13320- 1:1999,GB/T19077.1-2008,Q/0100JWN001-2013  This technique's ability to perfor...
