New Si Wafer ATR Elements for Spectroelectrochemistry

Oct 28 2019 Read 623 Times

The Jackfish Cell (SEC) from PIKE Technologies is a complete, out-of-the-box solution for surface-sensitive spectroelectrochemistry using the ATR-SEIRAS technique, which allows the collection of high-quality infrared spectra from submonolayer amounts of material at the electrode-solution interface. Designed and tested for use with the PIKE VeeMAX III variable angle specular reflectance accessory, the SEC is configurable with new ATR element options, microgrooved Si wafers. Due to the thin profile of the Si wafers, the user has access to the entire fingerprint and far-IR spectral regions Additionally, the wafers are relatively inexpensive and can be recycled or disposed of depending on the application.  

The Jackfish has several innovated design features to make ATR-SEIRAS measurements more reliable. As this sampling technique relies on a metal 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 metal films.
