We are no longer selling the 115U or 115E.

Spectroelectrochemistry is a coupled technique that combines spectroscopy and electrochemistry.  A potentiostat/galvanostat is used to induce chemical changes on a surface or within a solution that are then monitored by changes in a spectrum.  Spectroelectrochemistry especially useful for studying redox transitions of various species such as organometallic complexes and nanoparticles among others.

Product Details


Gamry’s three spectroelectrochemistry systems are the Spectro-115UTM (200 - 850 nm), Spectro-115ETM (350 - 1000 nm) and i-Raman (532 or 785 nm laser) . Each system utilizes a miniature CCD spectrometer, USB 3.0 communication, and temperature compensation. These fiber-based spectrometers can be easily configured for absorption or transmission. The UV/Vis systems interface with a deuterium/tungsten light source that has a spectral output of 200 - >1100 nm and can be configured to provide both D2 and W. The light source also includes a safety shutter.

Gamry Instruments partners with B&W Tek to supply you with these spectrometers.  Gamry's software allows for general control of these spectrometers.  If more explicit control is necessary for these spectrometers, you can download the BWSpec software from B&W Tek's website and then trigger acquisition using one of the digital outs from a Gamry potentiostat.  More information on triggering external devices can be found in our technical note.  Though Gamry does not actively support other spectrometers you can trigger external devices with any of our potentiostats.
