The Fritsch A28 Dynamic Image Analyzer is an advanced instrument used for measuring and analyzing particle size and shape.
It is specifically designed to investigate the morphology of powders and granules, making it a crucial role in laboratories and industries where accurate particle characterization is essential, such as in the pharmaceutical, chemical, and food industries.
The device is designed in accordance with ISO 13322-2, the standard in the pharmaceutical, chemical and material science industries for measuring particle size and shape according to the dynamic image analysis technique.
Basic principles and operation
The A28 Dynamic Image Analyzer uses dynamic imaging to analyze the particles. For dry material, this means putting the particles in motion by passing them through a vibrating chute to a measuring cell, where they are captured in free fall by a high-resolution camera.
The particles can also be measured wet. To do this, the particles are dispersed in water or another solvent. This liquid is pumped around and captured by the camera in a measuring cell. The speed and accuracy with which these images are captured make it possible to analyze a large number of particles in a short time, allowing a representative image of the material to be obtained.
Once the images are captured, they are analyzed in real time by powerful software. This software is capable of calculating a wide range of parameters, such as particle size, circumference, aspect ratio and round shape. This allows researchers and engineers not only to determine the size distribution of the particles, but also to obtain detailed information about the shape, which can be crucial to the properties of the final product.
Specifications and capabilities
The Fritsch A28 is equipped with a camera that can capture images at a very high resolution, down to a few micrometers, depending on the configuration. This makes it possible to analyze both very small and larger particles very precisely. Thanks to automated operation and efficient image processing software, large quantities of particles can be analyzed in just a few minutes. In addition, the system can be equipped with different lenses and exposure options, allowing it to be customized to the specific needs of the user.
Applications
The versatility of the Fritsch A28 Dynamic Image Analyzer makes it a valuable tool in a variety of industries. In the pharmaceutical industry, for example, it is used to check the consistency of powders, which is critical for drug dosage and solubility. In the food industry, it can be used to analyze the properties of powders, such as cocoa or sugar, which affects the texture and solubility of the final product.
The Fritsch A28 is also often used in the construction and chemical industries. For example, in the characterization of coarser materials in construction such as in the recycling of building materials, or in the analysis of catalysts and other chemical powders, where particle size and shape have a direct influence on reactivity and efficiency.
Conclusion
The Fritsch A28 Dynamic Image Analyzer is a powerful and versatile instrument that provides indispensable insights into particle size and shape. With its advanced image processing capabilities, fast analysis times, and broad application possibilities, it plays a key role in research and quality control in a wide range of industries. It combines precision, speed, and ease of use, making it a perfect alternative to both conventional sieve analysis and a microscope.
