Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To provide a simple and portable method for capturing a chemical substance by concentration by which it is possible to simply collect a gas without the use of a suction pump, a drive source or the like and further simply control a temperature. SOLUTION: This method for capturing a chemical substance by concentration is to selectively concentrate and capture the chemical substance dispersed in a gas using a capturing means. When introducing the chemical substance into a concentration means, the gas is collected without the use of a suction pump, a drive source or the like by using a phenomenon to be generated by a chemical reaction, and also a temperature is controlled without the use of a temperature control device. A first modality is to introduce the chemical substance into the capturing means using the volume contraction of the gas to be generated by a chemical reaction between a component contained in the gas and a reaction substance which undergoes a chemical reaction selectively with the contained component.  The second modality is to control the temperature of the capturing means using a reaction heat to be generated by the chemical reaction.
