Abstract :
Microemulsions are gaining increasing importance, e.g., in food industry and as systems providing microdomains for chemical reactions. For both, the research on and the preparation of microemulsions, monitoring the phase state is a crucial issue. We report on the utilization of permittivity and miniaturized viscosity sensors for this purpose.
