2.1. Measurement set-up
The measurement set-up for the characterisation of the
EIS pH and penicillin sensors consists of a commercial
single-line flow-injection analyzer FIA-Lab-2500 (FIA-Lab-
Instruments), an impedance analyzer (Zahner Elektrik) with
personal computer to control both the impedance and the
flow-injection analyzer, and the developed microcells with
integrated EIS sensors and a Ag/AgCl reference electrode.
