Ametek PARSTAT 4000A Potentiostat Galvanostat

The PARSTAT 4000A is the latest edition to the PARSTAT line of potentiostats.  As modular-design has become a focus within the industry, 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:

• Physical electrochemistry and electrochemical sensors -- Cyclic Voltammetry, Chronoamperometry, Chronopotentiometry, and EIS

• Bare-metal corrosion, galvanic couples and coatings -- Tafel, Linear Polarization Resistance (LPR), Electrochemical Noise, and EIS

• Batteries (Li-ion, Li-Air, Zn-Air), capacitors, and fuel cells -- Charge-Discharge, CC-CV, Constant Current and EIS

The new hardware-based, user-selectable Stability Modes further expands the compatibility of the PARSTAT4000A with a range of electrochemical cells and samples. The PARSTAT4000A now provides a vastly improved Electrochemical Impedance Spectroscopy (EIS) technique.  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

• Increased bandwidth for measurement up to 10 MHz

• Direct connection to energy-storage devices through the MACCOR battery holders eliminate impact from cell cable impedance

The PARSTAT 4000A can measure up to 4-Amps and includes a 40 pA range (1.2 fA resolution).  Additionally, options are available to boost the high current measurement to 20-Amps and extend measurements down to 80 fA (2.5 aA resolution).
