Accurate measurement of particle size is essential for the determination of the consistency, quality, and overall usefulness and performance characteristics of a material. The instrument selected for a particle sizing application must be appropriate for the material to be measured and for the environment in which the instrument is to be used. It also must provide data to meet the specific needs of the application. Accordingly, Micromeritics offers an extensive line of particle size analyzers that is based on a variety of measurement techniques. We’re happy to work with you to identify which technique best suits your specific applications requirements.

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.

The new generation SediGraph III 5120 Particle Size Analyzer combines a proven analytical technique with advanced instrumentation features to provide repeatable, accurate, and reproducible results. It determines particle size by the highly accurate and reproducible X-ray/sedimentation method, which measures the gravity-induced settling rates of different size particles in a liquid with known properties. Particles with diameters in the range of 300 to 0.1 µm can be measured with the SediGraph™ III 5120.

The Elzone® particle analyzers deliver fast, accurate, reproducible data on a broad spectrum of sample types. Based on a widely recognized particle characterization technique, the Elzone's electrozone method is ideal for sizing and counting a variety of particulate materials, both organic and inorganic. Elzone analyzers have the ability to measure low-concentration samples and can produce accurate data where analyzers using other techniques are limited.

The new MasterTech 052 Autosampler increases sample throughput, improves reproducibility, and requires less operator time for particle size analysis with the SediGraph or the Saturn DigiSizer. The MasterTech Autosampler increases throughput by ensuring there is no lapse between the completion of one analysis and the beginning of the next. Reduced operator involvement not only limits the possibility of human error, but saves time and increases repeatability and reproducibility. You can queue up to 18 samples to run sequentially and completely unattended. Operation of the MasterTech is controlled by the instrument's operating software with dispersion and redispersion information automatically stored in the sample file for future reference. One computer can control two instruments, each with its own MasterTech automatic sample feeder.
