NOVELTY - A multicomponent gas analyzer comprises chemical sensors and chemical sensor arrays that use chemo/electro-active materials to detect the presence of and/or calculate the concentration of individual gases within the multi-component gas system.    USE - The invention is used for analyzing gas components of multicomponent gas mixtures, e.g., nitrogen oxide, hydrocarbon such as butane, carbon monoxide, hydrogen sulfide, sulfur dioxide, halogen, hydrogen, water vapor, ammonia, and oxygen, in automobile emissions. It can also be used in diesel engines and home heating systems, in manufacturing processes, in waste streams, environmental monitoring or in systems in which odor detection is important, such as, in medical, agricultural, food and beverage industries.    ADVANTAGE - Unlike various prior art technologies, there is no need to separate the component gases of the mixture for purposes of performing an analysis, such as, by membrane or electrolytic cell. There is also no need when performing an analysis using this invention to employ a reference gas, to bring the response or analytical results back to a base line value    DETAILED DESCRIPTION - A multicomponent gas analyzer comprises:    (a) an array of at least two chemo/elector-active materials connected in parallel circuitry, each exhibiting a different electrical response characteristic upon exposure to the individual gas component than each other chemo/electro-active material;    (b) a device for determining an electrical response of each chemo/electro-active material upon exposure of the array to the gas mixture;    (c) a device for determining a value for the temperature of the array connected in parallel circuitry with the chemo/electro-active materials; and    (d) a device for digitizing the electrical responses and the temperature value, and calculating a value from the digitized electrical responses and temperature value, to perform an analysis of the individual gas component.    An INDEPENDENT CLAIM is included for a method for analyzing an individual gas component in a multi-component gas mixture comprising:    (1) providing an array of two chemo/electro-active materials;    (2) exposing the array to the gas mixture;    (3) determining an electrical response of each chemo/electro-active material upon exposure of the array to the gas mixture;    (4) determining a value for the temperature of the gas mixture;and    (5) digitizing the electrical responses and the temperature value, and calculating a value from the digitized electrical responses and temperature value to perform an analysis of the individual gas component.    DESCRIPTION OF DRAWING(S) - The figure shows a sensor array concept.
