CAMSIZER X2

Overview

The new CAMSIZER X2 provides particle size and shape distribution analysis needed for the quality control of fine powders and suspensions.

The design of the CAMSIZER X2 is based on the well-proven dynamic image analysis system CAMSIZER but is optimized for finer samples (from 0.8 µm to 8 mm). Both improved optical resolution and new options for material feeding allow for an extended application range. A range of sample presentation devices feed the sample to the measurement zone and provide the desired dispersion energy in order to de-agglomerate the sample without breaking individual particles. The CAMSIZER X2 offers the flexible X-Change system: the X-Fall module (free fall mode), which is the most gentle method for the material, the X-Jet module with adjustable pressure and variable nozzle geometry, and the X-Flow module in which particles are dispersed in liquids, optionally by ultrasound.

Industries and applications benefiting from size and shape analysis by the CAMSIZER X2 include fine powders such as sand, abrasives, food, polymers, crushed glass, building materials, metal and ore powders, and pharmaceutical powders/granules. Measurement time is ~ 1 to 3 min depending on the desired measuring statistics. Reported result parameters include smallest diameter, length, mean diameter, aspect ratio, symmetry, sphericity, and convexity. Results can easily and accurately match historic results from other techniques (sieves, microscopy, diffraction) with the appropriate selection of result parameters and automated software features.

The CAMSIZER X2 is manufactured by Retsch Technology GmbH and distributed in many parts of the world by HORIBA.

Measurement Techniques

The CAMSIZER X2 uses the principle of digital image processing. The patented  principle is fairly straightforward: dispersed particles pass in front of two bright, pulsed LED light sources. The shadows of the particles are captured with two digital cameras. One camera is optimized to analyse the small particles with high resolution, the other camera for the detection of the big particles with good statistics - that means large field of view. Each camera is illuminated by one LED with optimized brightness, pulse length and field of view. A user-friendly software analyzes the size and shape of each particle, and finally calculates the respective distribution curves in realtime.

Several sampling modules are available for measuring a wide range of samples from powders to suspensions. The X-Dry module is used for powders, and the X-Flow module for suspensions. Within the X-Dry module either the X-Jet or X-Fall inserts are used for sample presentation to the optics and dispersion. The X-Jet is optimized for fine powders and agglomerated materials requiring energy for proper dispersion. The X-Fall is ideal for larger free-flowing, non-agglomerated powders. The X-Flow module re-circulates liquid suspensions and can apply ultrasound to disperse agglomerates.
