摘要
A portable instrument for use in the field in detecting, identifying, quantifying, and monitoring gas, liquid or solid materials is disclosed. The instrument may analyze either liquids or gases depending upon the type of sensor array therein. The instrument also includes means for changing a gas, liquid or solid to a fluid material. The instrument further includes an array or small sensors which, upon exposure to the unknown material, form a pattern of electrical responses, a source of previously formed response patterns characteristic of various materials, and microprocessor means for comparing the sensor-formed response pattern with one or more previously-formed response patterns to thereby identify the material on a display. The number of responses may be increased by changing the operating voltage, temperature or other condition associated with one or more sensors to provide a plurality of responses from each of one or more of the sensors. The instrument is capable of identifying a large number of liquid and solid materials.
