Appeal No. 1996-1556
Application No. 08/154,135
The remaining claims, namely claims 11, 13, 14 and 18, stand
withdrawn from consideration by the examiner.
Claims 1 and 10 are representative of the subject matter
on appeal and read as follows:
1. A method of testing a sampled gas for the presence of a
selected analyte comprising the steps of:
providing an amperometric sensor, having a substantially
water-free, non-hygroscopic, water-insoluble, solid-state
electrolyte that has an ionic conductivity of at least 10 ohm -4 -
1-cm at room temperature, said sensor exhibiting sensitivity-1
to the selected analyte;
exposing said sensor to the sampled gas; and
measuring current flow in said sensor upon the presence
of said analyte in said sampled gas.
10. A method of producing an amperometric sensor for use in
detecting selected analytes which comprises:
applying a sensing electrode and a counter-electrode to a
solid-state electrolyte, and
providing a biasing circuit for applying a biasing
potential between said electrodes and a current-measuring
circuit for measuring the current between said electrodes that
is generated by the presence of said analyte,
said electrolyte being characterized by being
substantially water-free, non-hygroscopic, water-insoluble,
and having a composition resulting in an ionic conductivity of
-4 -1 -1
at least 10 ohm -cm at room temperature.
