Influence of an active vibration isolator and electrochemical cell design on electrochemical measurements to minimize natural convection

Abstract

The influence of an active vibration isolator (AVI) and electrochemical cell design on natural convection was investigated. The natural convection of an electrolyte caused by external vibrations and acoustic sounds is reduced by both an AVI and an acoustic enclosure. Slow scan voltammetry with an AVI shows a reproducible and predictable diffusion-controlled current down to 0.4 mV/s. Reducing the distance between the working electrode and the glass wall also has a considerable effect on the voltammetric signal.
