Abstract
A device and method for collecting, analyzing, and identifying chemical and biological samples in solid or liquid form is disclosed. The analysis compares the color change of Colorimetric Sensor Arrays (CSAs) over time with images for known materials/compounds contained in a library. The device can be used as a handheld or standalone device and integrates the sampling and detecting functions of the prior art into a single device that analyzes and identifies the sample without destroying it. The inventive volatile organic compound (VOC) technology device is also unique in that it relies on a comparison to a proprietary compound library that is supported by lab data. This compound library identifies the unique dye signature combinations that provide very accurate classification of a wide variety of chemical and biological agents.
