Proc. of SMSI 2021 Conference
We report on the design and fabrication of a dual electrochemical quartz crystal microbalance sensor unit with dissipation monitoring (EQCMD). Applying an electrical field between two oppositely placed quartz surfaces facilitates particle separation and monitoring the deposition of oppositely charged particles on the electrodes during or after the colloidal synthesis of silicalite-1 zeolites. By evaluating the resonance frequencies and quality factors of the quartz crystals, several properties of the test liquid are monitored indirectly. We demonstrate the measurement of electrical conductivity and viscosity.
