Abstract
A gas sensor having a housing with first and second chambers featuring a porous separator located there between. The first chamber of the sensor being connected to atmosphere via a gas diffusion aperture. The gas sensor having a sensing electrode disposed within the first chamber and at least a second electrode disposed within the second chamber. The sensor having an ionic liquid electrolyte disposed within the second chamber where the sensing electrode and at least second electrodes comprise platinum.
Claims10
An apparatus comprising:
- a housing having first and second chambers with a porous separator located there between and with the first chamber connected to atmosphere via a gas diffusion aperture;
- a sensing electrode disposed within the first chamber;
- at least a second electrode disposed within the second chamber;
- an ionic liquid electrolyte disposed within the second chamber where the sensing electrode and at least second electrodes further comprise platinum.

An apparatus comprising:
- a housing with first and second internal chambers divided by a separator and an aperture connecting the first chamber to atmosphere;
- a sensing electrode disposed within the first chamber;
- at least a second electrode disposed within the second chamber;
- an ionic liquid electrolyte disposed within the second chamber, where the sensing and at least second electrodes further comprise platinum and where the electrodes providing an output in response to hydrogen sulfide entering through the aperture without providing any significant output in response to carbon monoxide.

An apparatus comprising:
- a housing with first and second internal chambers divided by a separator and an aperture connecting the first chamber to atmosphere;
- a sensing electrode disposed within the first chamber;
- at least a second electrode disposed within the second chamber;
- an ionic liquid electrolyte disposed within the second chamber and saturating the separator thereby causing the sensing electrode to provide an output in response to hydrogen sulfide entering through the aperture, where the sensing and at least second electrodes further comprise platinum and where the sensing electrode does not provide any significant output in response to carbon monoxide.
