High impedance biosensors

Today Zimmer and Peacock had an enquiry as to whether the Ana Pot EIS was able to be used in biosensor applications, where the impedance was in the range 50 MOhm.  


Our answer to the client was yes, but to help the client our team made up a validation sensor that was 56 MOhm, with  a 0.1 nF capacitor in parallel with the resistor to give an imaginary component.

With our validation sensor we then tested on the Ana Pot EIS by scanning fro 100 mHz to 1 MHz, the results are below.
