Potentiostats/Galvanostats by Metrohm Autolab

 Autolab PGSTAT

Autolab PGSTAT-potentiostats for all electrochemical methods
The Autolab PGSTAT provides the scientist with all the electrochemical methods of interest for surface science. Potentiostatic and galvanostatic control allow the researchers to accurately control the reactions taking place at the electrochemical interface as well as the rate of these reaction and the quantity of material involved.

Using these methods, the composition, roughness, structure and growth mode of deposited materials can be controlled.
 

The Autolab EQCM module (Electrochemical Quartz Crystal Microbalance) further extends the versatility of the Autolab PGSTAT. It provides the means to measure mass changes in the ng/cm2 range.

This allows the users to detect the formation of the very first atomic layers on the surface of a piezo-electric quartz sensor. With this technology, the formation of metallic deposits during electrolytic or electroless processes can be monitored in situ.
