Applications and Software
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 expand the compatibility of the PARSTAT 4000A with a range of electrochemical cells and samples.
Impedance: Separation of electrochemical responses into individual contributions for improved understanding of the system under test.
The PARSTAT 4000A combines high accuracy, flexible measurement modes, and broad current/voltage ranges, making it a reliable choice for advanced electrochemical applications across energy, corrosion, materials science, and sensor research.
PARSTAT 3000A Potentiostat Galvanostat
The PARSTAT 3000A offers high voltage capability and features a 6-wire configuration for accurate anode/cathode impedance measurements.
☑️ Polarization voltage ranges of 6 Volts and 30 Volts, providing both range and resolution
☑️ 6-WIRE auxiliary voltage measurement for simultaneous EIS up to 7 MHz
☑️ Small footprint design without sacrificing power available
☑️ Technology available in bipotentiostat design as PARSTAT3000A-DX
☑️ Easy-to-use VersaStudio software included
Applications and Software
The PARSTAT 3000A is a high-performance potentiostat engineered into a small footprint for space-conscious laboratory and/or application environments.
The additional voltage measurement (6-WIRE) makes this instrument well-suited for Electrochemical Impedance Spectroscopy (EIS) on batteries, as two impedance values can be simultaneously acquired. Users can assign impedance values to anode and cathode; across separators; or to individual cells in a stack. Physical electrochemistry applications also benefit from using this input to capture pH measurements, temperature, or pressure by means of an external probe.
The Compliance Voltage (30 V) of the PARSTAT 3000A allows measurement in low conductivity (high impedance) solutions, such as ethanol, or when the Counter Electrode is isolated by a Bridge Tube with frit. Matching Polarization Voltage (30 V) gives the PARSTAT 3000A the ability to take full advantage of this high Compliance for potential control in electrophoretic deposition or high-voltage anodization.
The PARSTAT 3000A provides accurate EIS measurements up to 7 MHz. This is made possible by:
Advanced calibration routines for overall improved accuracy across the entire range of frequency and impedance.
Faster experiment duration, without sacrificing data quality typically associated with Multi-Sine EIS techniques.
New algorithms that provide increased accuracy of signal amplitude at high frequency.
Direct connection to energy-storage devices through the MACCOR battery holders that eliminate impact from cell cable impedance.
Through VersaStudio software, users can select from the different groups of techniques that are available:
➤ Energy 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).
