TEMPERATURE VARIATION FOR SENSOR ARRAY BASED DETECTION TECHNOLOGY

摘要

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.
