1. A sensor package, comprising:
- a housing having a recess formed therein, said recess having a perimeter and at least one passageway connected to said recess;
a solid state, planar electrochemical sensor underlying said recess,a gasket contacting said recess perimeter and said solid state, planar electrochemical sensor to form a seal therebetween; and
a contact lead assembly, comprising;
a contact lead frame having a first end and a second end; and
a plurality of leads having a first end secured to said first end of said frame and a second end adjacent to said second end of said frame, anda stabilizer ban extending between and contacting said plurality of leads, said housing, gasket and sensor defining a sample chamber.

Abstract
A solid state, multi-use electrochemical sensor having an electrically nonconductive substrate, a working electrode, and a semi-permeable membrane covering the working electrode. The working electrode includes an electrically conductive material adhered to a portion of the substrate. A first portion of the conductive material is covered with an electrically insulating dielectric coating, and a second portion of the conductive material is covered with an active layer. The active layer includes a catalytically active quantity of an enzyme carried by platinized carbon powder particles, which are distributed throughout the active layer. A sensor package for incorporating a sensor is provided.

18. An electrochemical sensor package, comprising:
-
a housing having a recess including an inlet and an outlet forming a flow path through said housing, said inlet having a first cross-section in a direction perpendicular to said flow path, said outlet having a second cross-section in a direction perpendicular to said flow path, said first cross-section being substantially equal to said second cross-section; a solid state planar electrochemical sensor; a gasket contacting said recess and said electrochemical sensor to form a sealed chamber; and a velocity compensator comprising a fixed in place structural barrier mounted in said flow path between said inlet and said outlet, a cross-section of said flow path in a direction perpendicular to said flow path at said velocity compensator being substantially equal to said first cross-section. - View Dependent Claims (19, 20)
