Abstract
The invention relates to a method and apparatus for providing a reactor having a heater, a passage for transporting a reactant, and a chamber containing a gas sample and being coupled to the passage for receiving the reactant and mixing the reactant with the gas sample. The reactor further includes a connector leading from the chamber to the heater for transporting a mixture of the reactant and gas sample, and wherein the heater heats the mixture of the reactant and gas sample.
Claims18
A reactor, comprising:
- a heater;
- a passage for transporting a reactant;
- a chamber containing a gas sample and being coupled to said passage for receiving the reactant and mixing the reactant with the gas sample;
- a connector leading from said chamber to said heater for transporting a mixture of the reactant and gas sample;
- and
- wherein said heater heats the mixture of the reactant and gas sample.
A reactor, comprising:
- a heater;
- a first passage for transporting a first reactant;
- a second passage for transporting a second reactant;
- a connector containing a gas sample and being coupled to said first passage for receiving the first reactant and mixing the first reactant with the gas sample;
- said connector extending from said first passage through said heater and coupling to said second passage for receiving the second reactant and mixing the first reactant and gas sample with the second reactant;
- and
- said second passage passing through said heater, whereby the second reactant, first reactant, and gas sample are heated by said heater.
A method for providing a reactor, comprising the steps of:
- premixing at least two reactant gases together;
- combining the premix of the at least two reactant gases with a gas sample;
- heating the premix and gas sample;
- and
- detecting a gas component in the gas sample using an electrochemical gas sensor having a substrate, an electrode deposited on a surface of the substrate, an ionomer membrane in contact with the surface and electrode, the ionomer membrane having a first surface and a second surface, and an opening in the ionomer membrane extending from the first surface to the second surface in a location proximate to the electrode, thereby defining a passage for providing diffusion control for the gas.
A method for providing a reactor, comprising the steps of:
- mixing a first reactant gas with a gas sample;
- heating the mixture of the first reactant gas with the gas sample prior to adding the second reactant gas,
- adding a second reactant gas to the first reactant gas and gas sample;
- heating the first reactant gas, second reactant gas, and gas sample;
- and
- detecting a gas component in the gas sample using an electrochemical gas sensor having a substrate, an electrode deposited on a surface of the substrate, an ionomer membrane in contact with the surface and electrode, the ionomer membrane having a first surface and a second surface, and an opening in the ionomer membrane extending from the first surface to the second surface in a location proximate to the electrode, thereby defining a passage for providing diffusion control for the gas.
