SEC-C Spectroelectrochemical Cell

ALS Japan brings to you two types of spectroelectrochemical cells:

Batch cell type: It uses a platinum or gold mesh electrode as the working electrode.

Flow cell type: It employs platinum, gold, and carbon grid, as well as ITO electrodes as the working electrode.
The flow cell type is designed for use in a standard spectrometer and is available in two optical path lengths (0.5 mm and 1.0 mm) with a 6.0 mm reference electrode.

These cells are used for spectroelectrochemistry, which investigates electrochemical reaction mechanisms and the interface structure between electrolyte solutions and electrodes.

More Information

Spectroelectrochemistry (SEC) focuses on studying electrochemical reaction mechanisms and the interface structure between electrolyte solutions and electrodes.

Advances in this field and its related technology have expanded SEC applications.

The relationship between absorbance and potential for reversible or quasi-reversible systems is now theoretically understood, enabling the analysis of electrochemical characteristics that are challenging to discern from voltammogram results alone.

Notable examples include the redox behavior of cytochrome c and methylene blue.

Features

Two optical path lengths: 0.5 mm and 1.0 mm
Compatible with a 6.0 mm reference electrode
Two types of working electrodes: gold (Au) or platinum (Pt)
Usable in a standard spectrometer

Comparison of 0.5 and 1.0 optical path length cell

The electrolysis stabilization time for the 0.5 mm optical path length cell is theoretically a half, compared with the 1.0 mm cell. It is the opposite, for the concentration, when the same result for the 1.0 mm cell is possible for a half of the concentration compared with the 0.5 mm cell. You could select the optical path length and the working electrode appropriate for your research purpose.
