Abstract

A new spectroelectrochemical method using the thermal-lens effect from electrolytes using regular joule heat generation by current focusing in a small-sized channel is proposed. The experimental dependences of the signal on the analyte concentration and applied voltage are in good concordance with the theoretical estimations. A cell design providing good reproducibility and sensitivity of measurements is proposed.
