SEC2000 - Spectroelectrochemical flow cell
The system is composed for spectrometer, light source, electrochemical analyzer, and spectroelectrochemical flow cell. Working electrodes (ITO, platinum mini-grid, and gold mini-grid) are replaceable. Reference electrode is an aqueous RE-3V reference electrode (Ag/AgCl) or non-aqueous RE-7V reference electrode system (Ag/Ag+). Working electrode’s grid distance is 150 µm, and line width is 100 µm. Gold electrode is very soft, when you clean the electrode surface with Kim wiper, it could damage the electrode surface, and so you may need to handle carefully.

Example of the simulation using SEC-F Spectroelectrochemical flow cell
In situ system response measurement using SEC-F cell was performed. CV with simultaneous absorbance measurement was performed in 10 mM Ferrocene in acetonitrile solution (Fig. 1). Formation of the reaction product and intermediate product, during CV measurement, was observed in real-time measurement of the absorbance (Fig. 2). And, Fig. 3 shows the absorbance peak.

Cyclic voltammogram (0 to 0.8 V; scan rate 50 mV/s), with simultaneous spectrum measurement, was performed using ITO electrode in Ferrocene solution. Oxidation and Reduction peaks were observed at 450 and 620 nm, respectively, as shown below (Fig.3).
