Turbiscan Stability Index (TSI) - Stability evaluation with just one click

The next step to Stability Comparison: The Turbiscan® device is well-known for providing substantial information on the stability and dispersibility of any formulation. Such data is obtained by monitoring the evolution of the backscattered and/or transmitted light intensities over time. However, in some cases it may be difficult to objectively analyze the data without an expert eye, for example in case of simultaneous destabilization phenomena (e.g. sedimentation and aggregation). Formulaction has developed a simple and robust criterium called the Turbiscan Stability Index (TSI) to rapidly compare and characterize stability of formulations. This application note describes how the TSI is calculated and provides with examples of use.
