Dynamic Image Analysis (DIA)

Dynamic Image Analysis (DIA) is a powerful state-of-the-art method for particle size and shape characterization of powders, granules and suspensions.

RETSCH Technology’s particle analyzers CAMSIZER P4 and CAMSIZER X2 use the principle of Dynamic Image Analysis. Thanks to the patented dual camera technology these analyzers cover a wide dynamic measuring range from 20 µm to 30 mm and from 0.8 µm to 8 mm respectively. The dual camera technology is based on the simultaneous operation of two cameras, allowing for the detection of fine as well as coarse particles in a wide measuring range with high resolution and efficiency.

Dynamic Image Analysis is used for quality and process control in many different industries and for a great variety of applications. Thanks to its superior features, DIA often replaces conventional methods like sieve analysis or laser diffraction. Compared to these methods, image analysis offers a number of advantages: a wealth of different size and shape parameters are obtained with high precision from every single particle image. Hence, the resolution of the measurement results is greatly superior to that of other technologies.
