Potentio Menu List

While it is possible to control a Generic Bioptentiostat via NanoScope 8.15 and the Analog 4 output of the NanoScope V controller, you will probably wish to control the potentiostat using the potentiostat vendor-supplied software. If you do not use NanoScope 8.15 to control the potentiostat, the only operable function in the Potentio menu is Hold which enables reading of the potentiostat by NanoScope 8.15. The remainder of this page discusses potentiostat control using NanoScope 8.15 software.

When the software is configured for an Electrochemistry (EC) mode, the Potentio pull-down menu, shown in Figure 1, appears in the NanoScope menu bar.

The items on this list modify the electrochemical cell voltage or current by altering the status and direction of the ramping of the ramp electrode.

• Hold:
  • Stops any ramp.
  • Holds the potentiostat at current values.
  • Continues reading cell potential, currents, and updates data values.
• Increase:
  • Increases cell potential from the current value to Ramp max (set in the Ramping Controls parameter list)
  • If current potential is larger than Ramp max, there is no change.
• Decrease:
  • Decreases cell potential from the current value to Ramp min (set in the Ramping Controls parameter list)
  • If the current potential is less than Ramp min, there is no change.
• CV Increase:
  • Starts a cyclic ramping from the current value to the Ramp maximum, then to the Ramp minimum, and repeats the cycle
• CV Decrease:
  • Starts a cyclic ramping from the current value to the Ramp minimum, then to the Ramp maximum, and repeats the cycle
• Stop All:
  • Stops the reading and updating of the potentiostat. The cell potential is still controlled at the last set value.

Off-line analysis of EC data is discussed in the NanoScope Analysis manual.
