Patent ID: 7518380

Claim:
A detector system comprising: a plurality of chemical impedance detectors; and wherein: each chemical impedance detector of the plurality of chemical impedance detectors comprises: a first terminal connected to a first plurality of finger-like electrodes; a second terminal connected to a second plurality of finger-like electrodes; a layer of polymer situated on the first plurality of finger-like electrodes, the second plurality of finger-like electrodes, and an area between the first plurality of finger-like electrodes and the second plurality of finger-like electrodes; wherein the first plurality of finger-like electrodes is intermeshed, but without contact, with the second plurality of finger-like electrodes: and wherein a first at least one chemical impedance detector of the plurality of chemical impedance detectors is situated proximate to an inlet of a fluid analyzer; and a second at least one chemical impedance detector of the plurality of chemical impedance detectors is situated proximate to an outlet of a fluid analyzer.
