Dynamic Shape Characterization (DSC)
The DSC is a shape characterization system for particles using in-situ image analysis of the sample. Digital particle images are collected and analysed on a vast range of shape parameters. The Video Microscope synchronized with a strobe light captures 'still' pictures continuously while particles are in dynamic ow. It is not necessary to stop the ow or limit monitoring to stationary objects. Multiple images are enhanced, processed, and analysed automatically to ensure full representation of the sample. Both image and statistical data can be printed or stored for a permanent record of the sample. The software intuitive interface simpli es work ow and speeds up image acquisition times while providing powerful features such as image stitching, object counting and volume views.
Modularity
Interchangeable measuring cell modules enable analy-sis of particles in virtually any state: liquids, powders, slurries, aerosols, pastes, thin lms and emulsions. Special cells facilitate the measurement of high concentrations.
With the I-mage 400, shape measurements on hundreds of thousands of particles from 1 micron to as large as 4,5 mm can be obtained in minutes. The I-mage features high optical quality with a high contrast image that facilitates the de nition and measurement of even low contrast objects
