LMP91000 cyclic voltammetry

Other Parts Discussed in Thread: LMP91000

Hello everybody,

I was wondering if any of you was able to successfully perform a cyclic voltammetry using the LMP91000. If you have done so, could you please walk me through the process of how you achieved it?

Thank you very much

    Andres,

    Though I have not performed cyclic voltammetry with the LMP91000 looking over the procedure at least at a high level it appears that the LMP91000 is capable of making this measurement. Basically sweeping the potential between the reference electrode (RE) and working electrode (WE) potential and measuring the current at the WE. The LMP91000 can provide both positive and negative bias, programmable from 0 to 24% VREF. Current from WE can be amplified with a programmable TIA_GAIN from 2.75K to 350K (or external resistor can be selected).  It will need to be validated that this biasing and amplification range meets the requirements of the application.

    I've forwarded to LMP91000 Apps Engineer to see if he has further insight.
