Sensor device
First Claim
1. An amperometric sensor device for detecting a predetermined component present in a fluid sample and providing an output representative thereof, the device comprising a permselective membrane incorporating a charged organic species, said permselective membrane being selective, by partitioning, for lipophilic species, and an electrode arrangement having a working electrode and a reference/pseudo-reference electrode, said electrodes of the electrode arrangement being in intimate contact with the membrane but not being exposed at the side thereof to be presented to the fluid sample and wherein said charged organic species provides a conducting path through the membrane between said electrodes of the electrode arrangement.

Abstract
An amperometric sensor device comprising a working electrode, a reference/pseudo-reference electrode and a permselective membrane incorporating a charged organic species. The electrodes are in intimate contact with the membrane and are on a side of the membrane opposite to the side exposed to a fluid sample. The charged organic species provides a conducting path through the membrane between the electrodes.
