The CAMSIZER in the context of pharmaceutical researchAssessment of Dynamic Image Analysis as a Surrogate Dissolution Test for a Coated Multiparticulate Product
Customer reference CAMSIZER® 2006Comparison of Camsizer-models (2004 and 2006) with three different other devices for measurement of particle size distributions: Laser light diffraction, sieve analysis and another device using digital image processing technique
Quality Control of Catalystst with Digital Image ProcessingCatalysts are widely used as an important auxiliary material in the pharmaceutical and chemical industry. They are able to accelerate chemical reactions by lowering the activation energy, i.e. they change reaction kinetics. Thus, using catalysts in industrial processes has the advantage of higher productivity combined with less energy consumption. In many processes a mixture of liquid or gaseous raw materials (e.g. petroleum) is transformed in a reactor with solid catalyst material. Depending on the desired reaction, catalysts of different materials such as ceramics, alumina, metal or alloys are used. To save costs, inexpensive substrates can be coated with the actual catalyst (e.g. platinum or rhodium). The active surface as well as the form of the catalysts is crucial for their efficiency. It is important that sufficient free volume is available for the reactants. Moreover, the counter pressure built up by the catalyst must not be too high. Spherical, comb-shaped or rod-shaped geometries have proven to be especially suitable. The rod-shaped catalysts have different shapes; their profiles can have an ellipsoid, trilobe or quadrulobe shape.
Process Optimization by modern Particle Size AnalysisThe high pressure to reduce the manufacturing costs of chemical starting products increasingly forces the manufacturers of such materials to a highly specialized production and quality control system.
Sieving Analysis vs. Image Processing: Salt MeasurementsNew evaluation methods in digital image processing have introduced a new dimension to the measurement of bulk goods in the food industry.
Particle Size and Shape Anaylsis in a Single MeasurementDigital image processing systems can be used for particle size analysis in ever-increasing sectors of the plastics industry – and also replace the traditional sieve analysis.
An optical-based system for particle size analysisA knowledge of particle size is of crucial importance for many processes in the bulk good industry. Compared to classical sieve analysis, the digital image processing method described in this article improves both the quality and efficiency of particle analysis in the micron to milimetre range.
Determination of the Roundness of Globules in the Pharmaceutical IndustryThe determination of grain size and roundness of globules and other vehicles in the pharmaceutical industry is of special interest.
Digital Image Processing with CAMSIZER®The measurement of bulk goods has entered a new dimension with the CAMSIZER. All the required particle size and shape analyses can be made in a single measurement, with the analytical results being compatible with traditional sieve analysis.

Comparability of Sieving Analysis and Image ProcessingA new means of evaluation give a different dimension to measuring bulk material by means of digital image processing.
CAMSIZER - Die zeitsparende AlternativeMit dem CAMSIZER von RETSCH Technology erhält die Vermessung von Schüttgütern eine neue Dimension. Mit einer einzigen Messung lassen sich alle gewünschten Partikelgrößen- und -formanalysen durchführen, wobei die Analysenergebnisse zur traditionellen Siebanalyse kompatibel sind.
Digitale Bildverarbeitung optimiert die Partikelgrößenanalyse von Sedimenten Die Korngrößenanalyse gehört von jeher zu den wichtigsten Untersuchungsmethoden in der Sedimentologie, wobei Sieb- und Schlämmanalyse noch immer die gängigsten Verfahren darstellen. Im Folgenden soll anhand einiger Beispiele verdeutlicht werden, wie die dynamische digitale Bildverarbeitung des CAMSIZER dank hoher Auflösung und hohem Probendurchsatz detaillierte Studien geologischer Prozesse ermöglicht.
