Potentiostat / Galvanostat / ZRA Gamry Reference 3020
Potentiostat / Galvanostat / ZRA Gamry Reference 3020
The high-end potentiostat for all demanding applications in electrochemistry, from very low to higher currentsThe Reference 3020™ is a high-performance potentiostat/galvanostat/ZRA with a maximum current of ±3.0 A (at a ±17.5 V measurement range) and a maximum voltage of ±36 V (at ±1.5 A).
The system is recommended for the development of batteries, electrolysers and fuel cells, as well as for general electrochemical measurements.
Product Description
The Reference 3020 Potentiostat / Galvanostat / ZRA is a high performance potentiostat, galvanostat, ZRA that offers considerable operating speed, a very wide current measurement range, low noise / hum, high sensitivity and unrivalled versatility with ease of use and connectivity to a wide range of electrochemical cells. The Reference 3020 Potentiostat / Galvanostat / ZRA can measure by sample impedance and frequency range with less than 1% error. It has rise times of 250 ns. Potential, current and an additional measurement input can be recorded with a data density of up to 3.3 µs per data point.
These impressive analogue and digital characteristics enable, for example, impressive theoretical scan rates of 1200 V∙s-1 for cyclic voltammograms with a step height of 4mV. In addition, the noise and hum in the Reference 3020 potentiostat / galvanostat / ZRA is conservatively specified at < 10 µV rms, and can be reduced even further by oversampling (fast sampling and averaging).
The Reference 3020 Potentiostat / Galvanostat / ZRA offers an adjustable potential of max. ± 32 V at the working electrode. With these hardware specifications, measurements can be made even in electrolytes with very low conductivity (high-purity water; concrete, organic electrolytes, etc.). The current at the working electrode is applied with a cable (working), while the potential is measured with a separate cable (working sense). Together with the cables for the counter electrode (Counter) and the reference electrode (Reference sense), four-wire measurements on batteries, membranes or films are easily possible while minimising the lead and connection resistances. In addition to the potentiostatic and galvanostatic measurement mode, the system offers the function of a zero resistance current meter (ZRA) for the observation of galvanic corrosion (bimetallic corrosion / contact corrosion) and the measurement of electrochemical noise.
For electrochemical measurements on earthed cells or cells with a working electrode in electrical contact with an earthed electrode through a conductive medium, e.g. in autoclaves, in connection with a tensile test in materials testing or on pipelines, a device with a floating mass is required. The Reference 3020 Potentiostat / Galvanostat / ZRA offers this without additional modification or options at extra cost. The floating earth of the Reference 3020 Potentiostat / Galvanostat / ZRA and all other Gamry potentiostats is realised by external switched-mode power supplies for the power supply, an additional internal switched-mode power supply with galvanic isolation and an opto-electronically decoupled USB connection.
Direct Digital Synthesis (DDS) circuits and sub-harmonic sampling are used for electrochemical impedance spectroscopy so that spectra between 1 MHz and 10 µHz can be recorded. In conjunction with the high number of current measurement ranges, this enables precise determination of impedances between 1012 Ω and 10-3 Ω.
