Aggregates Sizer - Specs

• Violet semiconductor laser (wavelength: 405 nm) is used for the semi-permanent light source. Maintenance, such as gas replacement, is unnecessary.
• The detector incorporates 78 elements at the front, one element at the side, and 5 elements at the back, for a total of 84 elements. Additionally, high-sensitivity light receptors that support Violet semiconductor laser wavelengths are adopted with all detectors.
• The fixed parts of the cell and cell holder can be pulled out at the front of the unit using a slide mechanism, as shown in the photo on the left. This makes it easy to mount and replace cells, and to perform maintenance.
• WingSALD bio standard software is supplied as standard. It offers versatile data processing and simple, high-speed operation to suit every purpose and processing requirement.

• High-concentration samples can be measured using the laser diffraction method.
• Measurement is possible by simply holding the high-concentration sample particles to be measured between two glass slides.
• Samples for which the particle size distribution would be changed by dilution can be measured in their original state, or with the minimum required level of dilution, and true images of the measurement object can be obtained.
• Commercial hand creams, face creams, and rinses can be measured with hardly any pretreatment.

• Measurement is possible with small amounts of sample (i.e., measured particles) and liquid medium (i.e., dispersion medium).
• The capacity of the batch cell is only 5cm3 so waste treatment for the suspension can be performed with relatively small amounts.
• The vertical motions of the stirring plate prevent sedimentation of the particles.
• The funnel reduces the possibility of sample spillage.
• A tetrafluoroethylene resin funnel is provided to reduce the possibility of suspension getting on the hands of the user. It also prevents the cell surface from becoming dirty.

The target particle size range is covered using a single measurement principle, single optical system, and single light source to achieve a perfectly seamless single wide range. Accurate particle size distribution measurements are possible across the entire measurement range using a single standard, as the instrument does not incorporate multiple optical systems that create discontinuities in the data.

The application of the SLIT optical system, based on sophisticated scattered light intensity tracing technology, smashes conventional wisdom to continuously capture forward-scattered light at up to a wide 60° angle on a single-detector face. This achieves high resolution in the fine particle region.

Forward diffracted/scattered light is detected by a “wing sensor II”, a 76-element sensor that was developed using semiconductor manufacturing technology of the highest level. This sensor can detect greatly fluctuating small-angle forward scattering with a high level of resolution and wide-angle scattering of low optical intensity with a high level of sensitivity. Also, side scattered light is detected by one sensor element and back scattered light is detected by four sensor elements. Accurately capturing light intensity distribution patterns with a total of 84 sensor elements enables the high-resolution, high-precision measurement of particle size distributions over a wide particle diameter range.

These analyzers incorporate powerful self-diagnostic functions. The output signals sent by the sensors and detecting elements, and the instrument operating status, can be checked, facilitating easier maintenance. Using the Operation Log function, detailed information about, for example, the instrument usage status and contamination of the cells is included with all the measurement data, making it possible to investigate the validity of measurement data obtained in the past.
