Description

Scientific methods can deliver a lot of information about your molecule, solution, or reaction, however, a single method will only provide a limited amount of information based on a single interaction, for example, light absorption, oxidation at an electrode, change of mobility, or movement of mass in an electric field. For this reason, scientists try to create hyphenated techniques that allow observing the same system at the same time with multiple techniques. A popular hyphenated technique is spectroelectrochemistry, where electrochemical reactions or products are characterized by electrochemical methods, e.g., cyclic voltammetry (CV), and spectroscopy, e.g. UV-VIS. The information both techniques deliver is complementary as well. For example, an unstable product of electrochemical oxidation can be detected by spectroscopy before it decays. This kit allows you to get started with spectroelectrochemistry in a convenient way. The spectroelectrochemistry application note will show you exactly how to connect the spectrometer to the potentiostat and operate the software to get your first results.

    Contents

    The Starter kit includes:

    Spectroelectrochemistry Starter Kit
    • A potentiostat of your preference: Nexus, PalmSens4 or EmStat4X (select ‘none’ if you wish to use an existing potentiostat);
    • Photoelectrochemical Cell ItalSens K300 with wires soldered to the electrodes;
    • Special cable to connect the Auxiliary port of a potentiostat to the Avantes spectrometer;
    • Easy-to-use PSTrace software.

    In addition to the starter kit, we have partnered with Avantes to offer you:

    • Spectrometer: the AvaSpec-ULS 2k (ULS2048CL-EVO), or the AvaSpec-Varius 2k (VRS2048CL-EVO) with improved optical bench design.
    • Light source AvaLight-DHc
    • Fibers 2x FC-UVIR600-1
    • Cuvette holder CUV-UV/VIS
    • AvaSoft software

    Together, this complete spectroelectrochemistry setup will look like this (laptop, pipettes and vials not included):
