2450-EC Graphical Potentiostat
Test Applications
The 2450-EC’s built-in scripting language enables
electrochemists, chemists, and materials scientists to
create libraries of reusable, customizable experimental
software for running tests including cyclic voltammetry,
chronoamperometry, chronopotentiometry, and more. The
following electrochemistry test scripts are loaded in the
internal memory of the 2450-EC.
• Cyclic Voltammetry: Potential is swept at a user
programmable scan rate between two to four
defined vertices while current is measured. Current is
measured using an analog integration method. This
application can also be used to perform Linear Sweep
Voltammetry.
• Open Circuit Potential: Measures the cell potential
difference between two electrodes with high input
impedance as a function of time.
• Potential Pulse and Square Wave with Current
Measure: The 2450-EC sources potential at
programmable peak and base levels and the resulting
current is recorded at the pulse peak level.
• Current Pulse and Square Wave with Voltage
Measure: The 2450-EC sources current at
programmable peak and base levels and the resulting
potential is recorded at the pulse peak level.
• Chronoamperometry: The potential is stepped to
a programmed value and the resulting current is
measured as a function of time.
• Chronopotentiometry: The current is stepped to
a programmed value and the resulting potential is
measured as a function of time.
In addition to pre-loaded test scripts, the built-in scripting
language enables the user to create their own library of
electrochemistry test scripts that can be modified as the
test and measurements evolve.
Built-in real-time graphing, charting, scope-like cursors, and data display spreadsheet for export simplifies converting test results into
useful information.
