A practical guide to choosing a potentiostat Pine Research

The electrolysis of water is your primary limiting factor when working in aqueous solvents. The potential window for water is roughly 1 to +1 V vs. the normal hydrogen electrode NHE. 1 This window can vary with supporting electrolyte, working electrode material, and pH, but as a ballpark estimate, your potentiostat does not likely need
