Analytical Instrumentation & Environmental Monitoring


Particle shape and size determination

August 2014 Analytical Instrumentation & Environmental Monitoring

The analysis of particle shape and size by digital image analysis with the new Analysette 28 ImageSizer and ImageTec from German-based Fritsch is effective, user-friendly and guarantees accurate results in the range of 20 μm – 20 mm. Especially useful for analysing dry, free-flowing powders and bulk solids, the optical analysis identifies particle shape and size, damaged particles, contaminates, agglomerates and over or undersized particles. These are recognised accurately and quickly and can be viewed as single images. The measuring time, depending on the sample quantity, is less than 5 minutes and results are available immediately.

The core of the Analysette 28 ImageSizer is a five megapixel camera, which assures highest resolution even with the smallest particles. The telecentric lenses guarantee images of each individual particle absolutely free of distortions and always in the same reproduction scale – no matter where it is located in the measurement volume. Up to 30 images per second can be generated due to the automated process. Any freely definable number of images can be recorded and evaluated.

It takes only three motions to complete an analysis: add the sample, start the measurement and read the result. This method offers a cost effective alternative to sieving due to fast and efficient size measurement. The evaluation and measuring is uniquely simple. Using software displays, each recorded particle is displayed as a data point in the Fritsch cloud, which shows important information regarding morphology. Other advantages of the technology include:

* Extensive library for morphological analysis.

* Practical tools for reliable quality monitoring.

* Simple operation via SOP control and report generator.
