Description:
In this video, I provide a detailed response to an inquiry regarding the electrochemical impedance spectroscopy (EIS) capabilities of the ZP SIA Potentiostat. The device, which I have on hand, is controlled via a dedicated application and utilizes QR codes for seamless navigation between various analytical methods.
I demonstrate how to activate EIS mode and outline key specifications, including frequency settings, DC voltage offsets, and AC voltage amplitudes. The frequency range can be set from 0.1 Hz to 200,000 Hz, with the option to scan in reverse order if required. Additionally, the DC offset voltage can be adjusted between -1 V and +1 V, while the AC voltage amplitude ranges from 1 mV to 50 mV.
Further information and relevant notes will be provided in the text accompanying this video.
