Spectroelectrochemistry with ATR-SEIRAS

Aug 09 2018 Read 539 Times

The Jackfish SEC Spectroelectrochemical Cell is a complete, out-of-the-box solution for surface-sensitive spectroelectrochemistry with the ATR-SEIRAS technique. Designed and tested for use with the Pike VeeMAX III variable angle specular reflectance accessory, the PTFE and glass cell can withstand aggressive cleaning and experimental conditions. The three-electrode cell can be purged with inert gas to remove dissolved oxygen, ensuring repeatable, high-quality electrochemistry.

ATR-SEIRAS relies on a Au thin film working electrode for surface-sensitivity. The Jackfish cell makes electrical contact with the film by using a unique spring-loaded pin design that is separated from the solution. This extends film lifetime, allowing the user to spend more time collecting experimental results and less time preparing Au films. High-quality infrared spectra can be obtained from submonolayer amounts of material at the electrode-solution interface. By using the Pike face-angled Si crystal, results can be obtained which outperform a conventional Si hemisphere in terms of signal-to-noise and absorbance band strength.
