Multiscan Stability Index (MSI) one-click stability evaluation

The MultiScan MS 20 from Dataphysics Instruments serves as an invaluable analytical instrument, offering comprehensive insight into the stability of any given dispersion formulation. The stability data is obtained by observing the evolving intensity of backscattered and/or transmitted light over a specified time frame. It can be difficult to conduct an objective analysis of the data in the absence of input from a qualified expert in cases where simultaneous destabilisation phenomena occur, such as sedimentation and aggregation. In response to this challenge, Dataphysics Instruments has developed a straightforward yet robust criterion, the Multiscan Stability Index (MSI), which enables the rapid comparison and characterisation of formulation stability. This application note describes the calculation of the MSI and provides illustrative examples of its use.
