Therefore, they imply to be an
attractive alternative as detectors for modern FIA equipments.
On the other hand, due to the greater simplicity
of the layout, the higher stability in the long term,
as well as the lower fabrication costs, a second type
of Si field-effect-based (bio-)chemical sensor, namely the
electrolyte-insulator-semiconductor (EIS) sensor is very
attractive for FIA applications [12–17].
