    Chronopotentiometry (CP)

    Electrochemical Impedance Spectroscopy (EIS)

    Frequency sweep, potential control
    (PEIS)

    (GEIS)
    During GEIS a current sine wave is applied and the resulting potential is measured. Continue reading
    Amplitude sweep (AC potential or current)
    The Impedance is measured at a fixed frequency varying the amplitude. The amplitude refers to the DC potential for potentiostatic mode, or DC current for galvanostatic mode.
    EIS Time Scan (IMPT)
    Fast EIS/GEIS
    The Fast EIS and Fast GEIS techniques provide a form of EIS where the latency between each measured datapoint is reduced to a minimum of 1 ms, starting at a frequency of 10 kHz. This allows for observing rapid impedance changes on a cell at a fixed frequency.

    Software

    PSTrace

    PSTrace is designed to be productive immediately after installation, without going through a long learning period.

PSTrace is suitable for all levels of user experience.

    Features include:

    • Direct validation of method parameters
    • Automated peak search
    • Equivalent Circuit Fitting
    • Scripting for running an automated sequence of measurements
    • Open data in Origin and Excel with one click of a button

    Software Development Kits

    PalmSens provides several Software Development Kits (SDKs) to help developers create custom software to control their potentiostat. Each SDK comes with documentation and examples that shows how to use the libraries.

    SDKs are available for:

    • .NET (WinForms, WPF and Xamarin for Android)
    • Python
    • LabVIEW
    • Matlab
    More information about our SDKs

    MethodSCRIPT™ Communications Protocol

    The Nexus works with MethodSCRIPT™, giving you full control over your potentiostat. The simple script language is parsed on-board, which means no DLLs or other type of code libraries are required. MethodSCRIPT™ allows for running all supported electrochemical techniques, making it easy to combine different measurements and other tasks. 

    MethodSCRIPT can be generated, edited, and executed in PSTrace.

    MethodSCRIPT features includes:

    • (Nested) loops and conditional logic support
    • User code during a measurement iteration
    • Exact timing control
    • Simple math operations on variables (add, sub, mul, div)
    • Data smoothing and peak detection
    • Digital I/O, for example for waiting for an external trigger
    • Logging results to internal storage or external SD card
    • Reading auxiliary values like pH or temperature
    • and many more…
