The PARSTAT 4000A stands alone in its ability to deliver high compliance voltage and wide dynamic current range, as standard, to cover a range of applications. The PARSTAT 4000A builds on PAR's history as the world-leader in DC electrochemical measurements and takes advantage of a common R/D team with Solartron Analytical, the world-leader in Frequency Response Analyzer (FRA) technology, to provide a best-in-class complete system.

Specifically, the PARSTAT 4000A has industry-leading DC Voltage Accuracy, both Applied and Measured. This is advantageous for all electrochemical experiments, whether operating as a potentiostat, galvanostat, or zero resistance ammeter (ZRA). The most common research areas and techniques that benefit from this improved accuracy are:

Energy: Batteries (Li-ion, Li-Air, Zn-Air), capacitors, and fuel cells -- providing charge-discharge curves (including CC-CV) for Capacity-vs-Cycle Number or Coulombic Efficiency as well as dedicated techniques such as Constant Power, Constant Resistance and Potentiostatic / Galvanostatic Intermittent Titration Technique (PITT, GITT)

Voltammetry Physical electrochemistry and electrochemical sensors -- providing fundamental electrochemical techniques such as Cyclic Voltammetry, Chrono-techniques. The Advanced Voltammetry techniques also include Pulse Voltammetry methods.

Corrosion: Bare-metal corrosion, galvanic couples and coatings -- providing multiple corrosion analysis techniques, including the most common ASTM standards such as Linear Polarization Resistance (LPR, ASTM G59), Tafel (ASTM G5), Cyclic Polarization (ASTM G61), etc. The new hardware-based, user-selectable Stability Modes further expands the compatibility of the PARSTAT4000A with a range of electrochemical cells and samples.

Impedance: Separation of electrochemical responses into individual contributions for improved understanding of system under test.
