Laser Diffraction
The Principles of Laser Diffraction
Laser diffraction has emerged as one of the most important and effective techniques in the world of particle size analysis thanks to its fast, non-destructive properties, its suitability for a broad range of particle sizes, and its ability to be fully automated. But what is laser diffraction, and how exactly does it work?
Before we delve into laser diffraction, it might be a good idea to provide a quick explanation of particle size analysis, otherwise referred to as particle size measurement. Particle size is often a crucial factor in determining the performance of a product or process. One example of this is the efficacy of ‘semisolid’ drugs, that are often used in ointments, creams, gels or lotions. Semisolid drugs have some of the properties of solids and some of the properties of liquids, so understanding the size of the particles they contain is crucial in knowing how each particular product should be delivered to the human body.
Facts About Laser Diffraction
As a technique of particle size analysis, laser diffraction is widely used and has many advantages. It offers a high level of precision, a fast speed of response, high potential for the repetition of results and a wide measurable particle diameter range. Particle size analysers offer a sophisticated way of measuring particle size and enable incredible insight and understanding of the particles that make up materials used in a range of industries.

Particle Size Analysis Basics
In many industries, the ability to determine the size of particles is not only useful but can be very important. A Laser diffraction particle size analyser is commonly used to provide this sort of information but the processes used to obtain particle size can be quite complex. Sampling, dispersion processes and the shape of materials all contribute to the complexity of particle size analysis.

Laser Diffraction – Why is it Such an Important Particle Sizing Technique?
As a technique of particle size analysis, laser diffraction offers the ability to learn more about particle size and shape with a high level of accuracy. This information is incredibly useful to industries and for research and the information generated is influential in streamlining and enhancing processes used.
Seven Facts About Laser Diffraction
Laser diffraction is one type of particle size analysis and is a technique known and respected across many applications for its ability to provide fast and reliable particle size data. In this type of particle size analysis, a cloud (or ‘ensemble’) of particles that is representative of the greater collection, travels through a broadened beam of laser light which scatters the light on to a specialised lens. Information about particle size and shape can then be deduced from the scattered pattern of light.
