Use of transimission and backscattering for dispersion stability analysis

The DataPhysics MultiScan MS 20 uses time- and space-resolved measurement of transmission and backscattering​ for dispersion stability analysis.

The analysis is an optical measuring procedure: with two light sources and a detector, the light transmitted through and scattered back by the sample is analysed. The transmission and backscattering intensities directly depend on the number, size and type of dispersed particles. Hence the light intensity changes while the dispersion destabilises. Stability analysis tracks these changes by scanning the sample repeatedly for a certain experiment duration. During the measurement the whole sample height is scanned, therefore both global and local changes in the sample are detected.
