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.
