Laser diffraction for particle sizing :: Anton Paar Wiki

Laser diffraction is one of the most common techniques for particle size analysis. It is based on the observation that the angle of (laser) light diffracted by a particle corresponds to the size of the particle. In a complex sample containing particles of different sizes, light diffraction results in a specific diffraction pattern.

Testing Particle Size by Laser Diffraction

The most current laser diffractors on the market have a very wide particle size range capability, usually anywhere from tens of nanometers (tenths of a micrometer) to greater than 3000 micrometers, and can be used on a liquid or dry dispersion basis. To put this in perspective, the diameter of an average human hair is approximately 50 to 70 ...

The DLS particle size analysis technique and laser diffraction method provide results which are based on different equivalent diameters and weighting models. For many samples, then, results measured with DLS and laser diffraction are not directly comparable and a deviation of 10 % or more between the results is to be expected.

Testing Particle Size by Laser Diffraction

Laser diffraction will produce a general particle size distribution. It should not be used if the goal is to identify a low quantity outlier population within a sample. A good example of this is polishing slurries where a small amount of large particulate can cause abrasion on the polished components.
