Pi Sentinel PRO Shape Module: Particle Shape Analysis Capability to Laser Diffraction

The Pi Sentinel PRO Shape Module (Pi SM) from Vision Analytical adds the potential of comprehensive particle shape analysis to laser diffraction and other similar size-only wet suspension technologies.

Besides determining particle size information, the Pi SM also reports up to 30 shape-related measures like size, as well as images of all measured samples.

The Pi SM has been configured in a way that it can be easily added to the fluidics line of users’ existing instrumentation. The system includes an all-in-one Windows-based computer for steadfast control of the Pi SM. The computer also provides a real-time display of particle images.

Once the analysis is done, users can match the particle size results from their traditional size-only instrument and the shape module.

The Pi SM has specifically been designed as an add-on component to size-only measurement techniques. The Pi SM can be added to users’ existing systems, thereby enabling the measurement of the same aliquot of sample for both systems.

A majority of the commercially available techniques assume particles to be spherical in nature while reporting the results; therefore, access to more shape information and particle images together with the results of existing techniques enables users to gain a better understanding of the particles and their performance during their final use.
