This is an entry level setup for photoelectrochemistry. It consists of a potentiostat, a LED revolver, a universal electrochemical cell and a set of electrodes: reference Ag/AgCl and platinum counter electrode.
The device is ready for two and three electrode measurements.
The LED revolver delivers irradiation from 1 of 10 LEDs in UV, VIS and NIR range. One can perform current measurements when potential and light intensity are scanned across set ranges.
A sample is placed in a PTFE electrochemical cell that handles both transparent and opaque substrates.
Although this is a simplified version of a full photoelectric spectrometer, it is rich in measurement possibilities.
