Abstract
A method for identification of a vapor sample or chemicals in a vapor sample includes introducing a vapor sample to a sensor array including a plurality of sensors, adjusting a temperature of one or more of the plurality of sensors between at least two temperature levels, and identifying the vapor sample or one or more chemicals in the vapor sample based on a plurality of response patterns of the sensor array, each of the response patterns being a collection of responses of the plurality of sensors to the vapor sample with the one or more sensors being at a different temperature level from among the at least two temperature levels.
Claims20
A method for identification of a vapor sample or one or more chemicals in a vapor sample, the method comprising:
- introducing a vapor sample to a sensor array including a plurality of sensors;
- adjusting a temperature of one or more of the plurality of sensors between at least two temperature levels;
- and
- identifying the vapor sample or one or more chemicals in the vapor sample based on a plurality of response patterns of the sensor array, each of the response patterns being a collection of responses of the plurality of sensors to the vapor sample with the one or more sensors being at a different temperature level from among the at least two temperature levels.
The method of claim 15, wherein the known response patterns are stored in the sensor library in association with temperature profiles specifying how temperature was controlled during the determination of the known response patterns, each of the temperature profiles defining a varying temperature level as a function of time or a set of discrete temperature levels.
A system for identification of a vapor sample or chemicals in a vapor sample, the system comprising:
- a sensor array including a plurality of sensors;
- a temperature controller that adjusts a temperature of one or more of the plurality of sensors between at least two temperature levels;
- and
- a chemical identifier that identifies a vapor sample introduced to the sensor array or one or more chemicals in a vapor sample introduced to the sensor array based on a plurality of response patterns of the sensor array, each of the response patterns being a collection of responses of the plurality of sensors to the vapor sample with the one or more sensors being at a different temperature level from among the at least two temperature levels.
A non-transitory program storage medium on which are stored instructions executable by a processor or programmable circuit to perform operations for identification of a vapor sample or chemicals in a vapor sample, the operations comprising:
- receiving a temperature profile defining a varying temperature level as a function of time or a set of discrete temperature levels;
- issuing a temperature control command in accordance with the temperature profile, the temperature control command for adjusting a temperature of one or more of a plurality of sensors included in a sensor array between at least two temperature levels;
- and
- identifying a vapor sample introduced to the sensor array or one or more chemicals in a vapor sample introduced to the sensor array based on a plurality of response patterns of the sensor array, each of the response patterns being a collection of responses of the plurality of sensors to the vapor sample with the one or more sensors being at a different temperature level from among the at least two temperature levels.
