Introduction to Dispersion Stability Analysis
Dispersions are multi-phase mixtures where substances are insoluble in one another. They include suspensions, emulsions, and foams, each with a continuous phase and dispersed particles. Stability is crucial for product development across various industries, as destabilization can lead to sedimentation or phase separation.

Measuring Principle of the MultiScan MS 20
The MultiScan MS 20 uses optical measurement with light sources and a detector to analyze transmitted and backscattered light. Changes in light intensity indicate destabilization, such as sedimentation or clustering of particles. The system scans the entire sample height to detect both global and local changes.

Case Study: Protein Shake Stability
A commercial protein shake was tested using the MS 20. The analysis detected unstable components and distinguished destabilization mechanisms. Initial migration of particles was observed, followed by a stable phase and further migration, indicating sedimentation.

Features of the MultiScan MS 20
The MS 20 is a fast, sensitive, and non-destructive device for analyzing dispersion stability. It can handle various dispersions and measure under realistic conditions. The device includes a touch screen for control and can use multiple ScanTowers for different temperature settings. It supports both reusable and disposable sample containers.

MSC Software Capabilities
The MSC software facilitates measurement setup and data analysis. It offers templates, graphical data representation, and various analysis options, including sedimentation and creaming rates. It also calculates particle size distribution and supports ASTM standards.

Technical Specifications
The MS 20 supports sample containers of different sizes, with a scanning range of 0 to 56.5 mm and a maximum resolution of 5 µm. It operates with a near-infrared LED light source and can measure temperatures from 4°C to 80°C. The device can handle up to six samples simultaneously and is controlled via a touch screen and software.
