Particle Characterization

Particle Characterization Explained

There is a wide range of commercially available particle characterization techniques that can be used to measure particulate samples. Each has its relative strengths and limitations and there is no universally applicable technique for all samples and all situations.

Which particle characterization techniques do I need?

A number of criteria must be considered when deciding which particle characterization techniques you need:
• which particle properties are important to me?
• what particle size range do I want to work over?
• are my samples polydisperse i.e. do I need a wide dynamic range?
• how quickly do I need to be able to make measurements?
• do I need to measure at high resolution?
• do I need good statistical sampling for robust QC measurement?
• do I need to disperse my sample wet or dry?
• how much money am I prepared to spend?

The following table is designed to provide some basic guidelines to help you decide which of some of the commonly used techniques could be most suitable for a particular application. The particle size ranges indicated are a guide only and exact specifications may vary from one instrument to another.
