Learn more about laser diffraction with Microtrac’s application notes

Metal Powders Manufacturing – Morphological properties, which include size and shape, are important quality control specification parameters for metal powders. These properties are important for outgoing QC for metal powder manufacturers and incoming QC for powder metalllurgy parts manufacturers.

Particle Size Measurement of Cement by Laser Diffraction – The manufacture of cement depends upon many factors, including chemical composition of raw materials, firing temperatures, and particle size. Of particular interest in this note is particle size measurement, since it can affect the efficiency of process grinding and quality of the final product.

Use of Power Generation By-Products in Wallboard, Cement, and Plastics – This paper provides a short outline of some of the advances and positive actions taken by the electric power companies to comply with the Clean Air Act by using by-products of coal burning for electric power.

Unified Scatter Technique for Full Range Particle Size Measurement – This paper provides a short summary of the history of different analytical techniques used to provide a complete particle size distribution and their benefits.

A Conceptual, Non-Mathematical Explanation on the Use of Refractive Index on the Particle Size Measurement – This paper provides a detailed analysis of the effect of the refractive index on the particle size distribution.

Powder Coatings and Particle Size Measurement – Powder particle size can have a major influence on many properties, including handling, charging, delivery, and coating characteristics. The formulations may vary depending on application requirements of thickness, object shape, and ambient conditions.

Pigment Particle Size Measurement – This note describes the more general measurement of all pigment types using the Microtrac patented tri-laser diffraction analyser.

Benefits of Using Blue Lasers for Particle Size Measurement – The Tri-Laser system has been upgraded to include blue lasers to provide advances in resolution and sensitivity in the submicron and nanosize ranges. The concept of utilising logarithmic detector design to provide shift-invariance described for tri-laser systems is maintained and extended to the combined use of blue and near-infrared lasers.

Accurate Particle Sizing Significantly Improves Processibility of Polymers – This note explains in detail the benefits of using particle size measurements to understand the complex process involved to make polymers.

The Importance of Representative Sampling and Dispersion for Dry Powder Particle Size Measurements Using Laser Diffraction – This application note explains the importance of representative sampling and dispersion for accurate particle size measurements of dry powders when using laser diffraction technology.

Using Laser Diffraction Particle Size Analysis to Monitor Fines During the Chocolate Production Process – This application note explains how laser diffraction particle size analysis can be used to measure fine particles during the production process of chocolate.
