Potentiostat for electric and photoelectric characterization of samples

Description

Potentiostat is an universal, experimental device that allows to apply various measurement techniques. Device may be used in two and three electrodes setup and can handle up to two external photodiodes. The instrument is capable of measuring currents down to 1 pA.

The device may serve also as a Controller for multiple other instruments from Instytut Fotonowy.

Techniques and quantities measured by the instrument:

Electric current of the sample,
Chronoamperometry (CA),
Photocurrent of the sample illuminated with white or monochromatic light,
 Open Circuit Potential (OCP),
 Cyclic voltammetry (CV),
 I-V characteristics,
