Corrosion resistance measurements

    VersaSTAT 3 (Princeton Applied Research)

    The following groups of techniques are available:

    • Corrosion providing multiple corrosion analysis techniques such as LPR, Tafel, cyclic polarization, etc.
    • Voltammetry providing basic and advanced scan, step and pulse electrochemical techniques.
    • Electrochemical impedance spectroscopy providing impedance data of the system by applying a sinusoidal signal with variable amplitude and frequency (in AC).

      Voltage Control (potentiostat mode):

      • Voltage range ±10 V
      • Voltage resolution 300 nV, 3 µV, 30 µV, 300 µV
      • Maximum scan range ±10 V / 300 µV

      Current Control (galvanostat mode):

      • Current range ±650 mA (standard), ±2 A (optional)
      • Current resolution ±1/32.000 x full scale
      • Current accuracy ±0.2 % of reading value
      • Min. current range /resolution: ±200 nA / 60 pA

    Impedance specifications

    • Frequency Range 10 μHz – 1 MHz
    • Maximum AC Voltage Amplitude 1000 mV RMS
    • Minimum AC Voltage Amplitude 0.1 mV RMS

      The VersaSTAT-3  potentiostat/galvanostat combines an electrochemistry cell and probe cartridge designed for AFM/STM microscopy system Innova (Veeco). The module  permits in situ Contact mode or STM studies of surfaces in a controlled electrochemical environment.  Scans and electrochemical measurements can be taken simultaneously using V3 Studio Electrochemical software package. Analysis of the impedance data can be performed by equivalent circuit fitting using Zview software.
