SEC-C Thin Layer Quartz Glass Spectroelectrochemical cell kit uses platinum or gold mesh electrode as a working electrode. We offer 0.5 and 1.0 mm optical path length cells. After setting the mesh electrode, the activity area for the cell is about 6 mm diameter with a center at 15 mm of the bottom. For reference electrode, the RE-1B or RE-7 is recommended.

Optical path length 1.0 mm cellThe optical path length 1.0 mm is most suitable for basic spectrum electrochemistry measurements. Theoretically, it is possible to get the same result as for 0.5 mm with a half concentration sample.

Optical path length 0.5 mm cellThe optical path length 0.5 mm has an electrolysis time shorter than 1.0 mm cell. The stability short time for the electrolysis makes possible to have a stable result as for, measurement of the high volatile organic solvent, detection of the unstable electrolysis products, and others. ∗There is a specific working electrode for 0.5 mm optical path length. The working electrode for 1.0 mm optical path length can not be used in 0.5 mm optical path length quartz cell.

Measurement example using cuvette type spectroelectrochemical cell | ||
UV-visible absorption spectrum and absorbance of the product of the electrode reaction, performed with optically transparent electrode (OTE), were measured. Gold or Platinum mesh electrode was used as an OTE. Absorbance (Figure 2-2) and the oxidation and reduction results (Figure 3-1, 3-2) of the 1 mM potassium ferrocyanide, as the reference of the absorbance, performed in a SEC-C Thin Layer Quartz Glass Spectroelectrochemical cell are shown below. | ||
