The Saturn DigiSizer®II is the first commercially available particle sizing instrument to employ the light scattering analysis technique that utilizes advanced digital detection technology to deliver exceptionally high levels of resolution, accuracy, repeatability, and reproducibility. A state-of-the-art CCD detector containing over three million detector elements enables the completely automated Saturn DigiSizer II to capture a high resolution, digital representation of the pattern produced as a result of laser light scattered from a sample. The resulting information is then processed using data reduction based on Mie theory. The instrument produces fast, detailed results that are repeatable on and reproducible between every Saturn DigiSizer.


Saturn DigiSizer II


High-Definition Digital Particle Size Analyzer


Particle sizing techniques have advanced significantly throughout the past several decades. One of the most important contributions to this field is the application of laser-based technologies, complemented with the use of modern photo-detectors and digital computers. For some time, progress in laser light scattering technology has led to faster analyses, but the quality of the measurement was limited, often due to inadequacies in the detector.


Recognizing this need for better detection capability, Micromeritics developed the Saturn DigiSizer, an instrument that employed a laser diode and modern charge-coupled device (CCD) detector to significantly improve the sensitivity, resolution, reproducibility, and repeatability of the laser light scattering particle sizing technique.





Sensitivity, High Resolution, Reproducibility, Repeatability


With the Saturn DigiSizer II, Micromeritics has again improved this particle size technique. Utilizing a state-of-the-art CCD detector containing over three million detector elements, Mie theory, and unique design and data reduction features, the Saturn DigiSizer II gives users an extremely high level of resolution and sensitivity not available in other laser particle sizing systems. The level of detail, accuracy, and resolution enables the extraction of all available information from the static light scattering pattern. Users can now measure the same material on multiple instruments located at different locations around the world and get the same, highly detailed size distribution measurement on each instrument. The Saturn DigiSizer II is fully automated and requires little operator intervention.
