Phase Behavior
Phase behavior of solutions containing surfactants and/or polymers has been subject to research over many years. Still there is need for the determination of phase boundaries, polymer chain dimensions, complexes between polymers and surfactants etc.
It is fundamental to know the phase behavior of solutions since the phase behavior at surfaces is very similar but occurs at other concentrations.
Light scattering
Light scattering, classical or dynamic, is a classical tool to determine the solution properties of polymers and surfactants. Light scattering allows the determination of both aggregate size and shape and can be used to determine pre-aggregation tendencies in solutions.
Fluorescence spectrometer
Determination of fluorescence is used for the analysis of aggregate size, for example size determination of solubilizing micelles. It can also be used for determining the interaction between components in solution.
