Static Image Analysis

The new particle size / particle shape analyzer CAMSIZER M1 is designed for precise characterization of powders and suspensions down to the low micron range by static image analysis. The CAMSIZER M1 offers great flexibility for the measurement of a wide variety of sample materials. The fully automated analysis technique ensures objective and user-independent evaluation, making the CAMSIZER M1 an ideal tool for applications in R&D but also for routine analyses.

The CAMSIZER M1 particle size / particle shape analyzer features a powerful illumination unit, a highly precise sample stage and five objectives with magnifications from 2.5 x to 50 x. Thanks to the wide traversing range of the sample stage, an area corresponding to up to eight standard object slides can be evaluated. The CAMSIZER M1 uses an 18.1 Megapixel color camera for image acquisition which guarantees rapid and accurate particle analysis over the entire measuring range.

APPLICATION EXAMPLES

active pharmaceutical ingredients and excipients, cement, ceramic powder, chemicals, fibers, fine grinding and polishing agents, food, industrial diamonds, metal powders, minerals, …

FEATURES

FUNCTION PRINCIPLE

The CAMSIZER M1 uses the principle of static image analysis to determine the particle size and particle shape in a measuring range from 0.5 µm to 1500 µm. An object slide with sample material is shifted stepwise along a camera system which acquires one image per step. The samples may be dry or wet (powders or suspensions). In contrast to dynamic image analysis, the sample is stationary during the measurement process; hence, the particle images show excellent quality and richness of detail.

At the start of each measurement, the particle size / particle shape analyzer CAMSIZER M1 determines the focal plane for the measurement area which ensures that all particle images in the selected area are pin-sharp (tilt compensation). All image and measurement data can be stored during analysis, providing manifold possibilities for subsequent data evaluation with the Particle X-Plorer module. When the measurement is finished, an overview image gives the user a good idea of the particle quality. Particles stretching over more than one measurement field can be pieced together by using the innovative stitching algorithm and may thus be evaluated although their size is larger than 1500 microns.
