Hi, I am looking for an impedance analyzer that is suitable for measuring changing of impedance in response to different protein concentration in body fluid. The technique is EIS, the impedance is measured by applying small ac voltage  (30-100 mV), in frequency range from 10^-3 to 10^5 Hz. The current generated is usually very small. from pico to milli Ampe. In paper, an instrument from Gamry, Reference 600 is used.


So I wonder which instrument from ADI has relevant specifications, usually used for sensor development and coating characterization? If there are anybody having experience with these, please provide me with suitable advice.


Kindly, TN.
