SEC-2F Spectroelectrochemical flow cell
Features:
• Thin-layer cell measurement
• Direct set to SEC2000 Spectrometer
• A variety of working electrodes
• Connection with an optical fiber
Using the spectroelectrochemical flow cell, it is possible to have a different optical path length changing the gasket.
We offer, as an optional item, a silicon and Teflon gasket with a 100, 250 and 500 µm of the thickness.
SEC-2F Spectroelectrochemical flow cell was designed to fit perfectly in the SEC2000 Spectrometer, and it eliminated the use of the optical fiber to connect the Spectrometer to the SEC-2F.
Even for another brand of the spectrometer, you can connect the SEC-2F using the collimating lens and optical fiber.
Configuration for Spectroelectrochemical measurement
∗ collimating lens, optical fiber and reference electrode are not included in the kit.

General setup for SEC-2F Spectroelectrochemical flow cell
Measurement example
Comparison of the absorbance for different gasket thickness
Measurement of the absorbance for potassium ferrocyanide electrolysis was performed using
100, 250 and 500 µm thickness gasket.
At the left diagram, the characteristic absorption peak of the sample is enclosed at a red line. At the right diagram, the equilimbrium time for electrolysis is shown.
Comparison of the absorption spectrum
The absorption spectrum response for different sample is shown in the clip below.
Application example
Electrolysis of Vitamin B12 derived complex.
The 250 µm gasket was used for the moritoring of the electrolysis spectrum of the vitamin B12 complex.
