BeScan Lab – Determination of Dispersion Stability
The BeScan Lab is a device for determining the stability of dispersions and formulations using static multiple light scattering (SMLS). Suspensions, emulsions or foams can be analyzed in their original state (up to 95% by volume) and at temperatures up to 80 °C. The BeScan is useful for quality control of various formulations, for example, to optimize storage stability, and also for quantitative analysis of different destabilization phenomena.

Static Multiple Light Scattering (SMLS)
Static Multiple Light Scattering (SMLS) is an optical method to characterize sample in terms of stability. The measurement can be carried out without changing the sample’s initial state. Two detectors are available:
- For concentrated samples, a backward detector is utilized to detect backscattered signals.
- For diluted samples, the transmitted signals can be detected by the forward detector. Therefore, transmitted signals are used for stability analysis.
Dispersion stability and Sedimentation analysis
By measuring the scattered light intensity in transmission and backscattering, it is possible to analyze highly concentrated systems. This allows the identification of various phenomena such as sedimentation, framing, flocculation, coalescence or phase separation. For this purpose, the sample is analyzed several times over the entire height in order to detect changes in transmission/backscattering as a function of height and time. With a resolution of 20 µm, destabilization processes can be detected much faster than with the naked eye. In addition, analyses at up to 80 °C can accelerate destabilization effects and measurements can be carried out as a function of a temperature ramp.
