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.

Figure 2 Influence on the reagent and product during CV measurement. |
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).
