By using laser diffraction to measure particle size, this technique allows the analysis of particle behavior and consistency in a range of products. Understanding particle size gives manufacturers the information and control needed to ensure the delivery of high-quality products across a variety of industries.
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.
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.
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.
1st April 2013. When undertaking particle size measurements it is important to validate the analysis method to ascertain both its robustness and integrity. Steve Ward-Smith and Alan Rawle review the steps that should be taken when validating laser diffraction methods for particle size analysis. Users of laser diffraction instruments for ...
Conclusions. Laser diffraction is a fast and effective technique for measuring the particle size of cement. The size range of the Mastersizer is ideally suited to measuring material over broad size ranges. For example, measurements of raw mix to extra fine cement grades can be made without having to change any lenses.
For the majority of processors, laser diffraction is the technique chosen to fulfil the associated requirement for particle size data. In this article, we examine how particle size defines the behaviour of metal powders and consider the merits of laser diffraction analysis within this context. Data are presented from both laboratory and process ...

Laser diffraction is the established and most efficient light scattering method for particle size analysis covering a wide range from submicron to millimetre scale. In the early 1980s, Sympatec introduced a breakthrough innovation which was leading laser diffraction to another dimension: dry powder dispersion for even the finest, cohesive ...
The laser light diffraction technique used for the determination of particle-size distribution is based on the analysis of the diffraction pattern produced when particles are exposed to a beam of monochromatic light. Historically, the early laser diffraction instruments only used scattering at small angles. However, the technique has since been
Laser Diffraction Particle Size Analysis (PSA) $250 / Sample i Add to Quote Example Outputs Two identical batches of catalysts (numbered 3 and 4) were placed in a reactor for differing lengths of time (Batch 4 had the longer reactor time).
2. Methods of particle size determination Apart from laser diffraction and sieve analysis, there are other methods for the size distribution assessment of solid particles such as sedimentation method, microscopic image analysis etc. The sedimentation method is one of the traditional methods of particle size analysis applicable to particles 0 ...

Laser diffraction is used for the determination of particle size distribution (PSD). The particle size distribution measured by laser diffraction is helpful for: Detection of batch-to-batch variations. Test the influence of production changes on the particles. Study if the PSD is a critical quality attribute for the manufacturing process.
The laser-diffraction PSA size distribution from both batches are overlaid to show increased prevalence of smaller particles (0.1 - 10 micron equivalent spherical diameter) in Batch 4. Particle size analysis (PSA) is an indirect, optical technique used to measure particle size distributions – by equivalent spherical diameter (D10, D50, D90 ...
