Abstract
An apparatus for sensing at least one analyte in a gas. The apparatus includes a thermoelectric sensor having a layer of at least one analyte interactant that increases or decreases in temperature and at least one thermopile having a first contact pad and a second contact pad, wherein the analyte contacts the interactant and produces or consumes heat, which is transmitted to the thermopile, produces a voltage difference and measures the analyte.
Claims50
An apparatus for sensing at least one analyte in a gas, the apparatus comprising:
- a thermoelectric sensor, the sensor comprising a layer of at least one analyte interactant that increases or decreases in temperature and at least one thermopile, said at least one thermopile having a first contact pad and a second contact pad;
- wherein the analyte contacts the interactant and produces or consumes heat, which is transmitted to the thermopile, produces a voltage difference and measures the analyte.
A method of detecting an analyte in a gas by thermoelectric sensor, the method comprising
- a. providing a thermoelectric sensor, the sensor comprising
- i. a layer of at least one analyte interactant that when combined with the analyte, gives off or consumes heat;
- and
- ii. at least one thermopile to which the heat change is transferred, which then registers a voltage difference;
- b. contacting the interactant of the thermoelectric sensor with the analyte;
- and
- c. indicating the presence or quantity of the analyte.
An apparatus for detecting analytes in fluids comprising:
- a) a conduit for channeling said analyte containing fluid past a two or more analyte reaction surfaces in series, said reaction surfaces being coated with an interactant that takes up said analyte and reacts with it to produce a physical reaction that can be sensed;
- b) a plurality of sensors disposed to detect said physical reaction;
- and
- c) at least one replenishment region disposed between said at least two analyte reaction surfaces, whereby analyte concentration in said fluid that was depleted by said take up replenished.
