Potentiostat/Galvanostat (Basis of specifications: Gamry Instruments, Model: 620 Potentiostat /Galvanostat /ZRA) • Qty: 2 • The equipment needs to be capable of operating in 3 modes: Potentiostat, Galvanostat, and Zero Resistance Ammeter. • The equipment needs to perform EIS Impedance from 10 microHertz to 5 megaHertz with an accuracy of less than 1% for impedance and less than 1° for phase angle. • The Potentiostat must incorporate at least 11 current ranges from 600 milliamps to 60 picoamps in a decade’s sequence without adding a low current module or gain amplifier. • The instrument must exhibit a voltage resolution of 1 microvolt and a current resolution of 20 attoamps (1 attoamps = 1 x 10-18 amps). • The Potentiostat must be compatible with commercial software to perform various electrochemical experiments, such as electrochemical impedance spectroscopy, electrochemical frequency modulation, cyclic voltammetry, pulse voltammetry, and DC corrosion.
