<p>A system for detecting a chemical substance which comprises a substrate (10) for the adhesion of a chemical substance contained in a gas to be measured, an adhesion percentage enhancing means (12) for accelerating the adhesion onto the substrate (10) of the chemical substance contained in a gas to be measured, an infrared ray source (20) for letting an infrared ray into the substrate having the chemical substance adhered thereon, and an infrared detector (22) for detecting the infrared ray coming out of the substrate after multiple reflection within the substrate (10). The system can be used for detecting a chemical substance in the environment quickly with high sensitivity.</p> |
