Monitoring Particle Sedimentation in Conductive Suspensions with Moving Electrode Impedance Spectroscopy

We devised a method to monitor the sedimentation of particles from conductive solutions by means of moving electrode electrochemical impedance spectroscopy. Measuring impedance spectra at different electrode spacings allows an isolated view on the electrolyte properties while simultaneously studying sedimentation processes. We present an experimental setup and propose application, for instance, to monitor crystallization processes in ionic liquids for the use of zeolite synthesis.
