Therefore, in this work, more detailed experiments have
been performed with pH- and penicillin-sensitive EIS sensors
(Al/Si/SiO2/Ta2O5 and penicillinase) in order to investigate
their successful integration into a commercial FIA system.
For the integration of the EIS sensors into the FIA set-up,
two types of flow-through microcells have been developed
with different layouts. In this context, the term “micro” is
not absolutely related to the cell size but also to the cell volume
[21].
