Abstract
Embodiments of the present invention relate to a gas sensor system comprising a gas sensor, a fluid reservoir enclosing a fluid and in proximity to the gas sensor and a membrane positioned between the gas sensor and fluid reservoir, wherein the membrane allows a sufficient amount of a test gas generated from the fluid to contact the gas sensor for testing. Embodiments also relate to a method of testing a gas sensor, the method comprises contacting reagents within a fluid reservoir, generating a test gas and contacting a gas sensor with the test gas sufficient to test the gas sensor.

A gas sensor system comprising:
- a gas sensor;
- a fluid reservoir, enclosing a fluid and in proximity to the gas sensor;
- and
- a membrane, positioned between the gas sensor and fluid reservoir;
- wherein the membrane allows a sufficient amount of a test gas generated from the fluid to contact the gas sensor for testing.
A gas sensor system comprising:
