GAS DETECTOR AND PROCESS FOR MANUFACTURING THE SAME

摘要

A gas detector that is capable of detecting various gases, for example, amine gases such as ammonia and pyridine, sulfurous gases such as hydrogen sulfide and methylmercaptan, aldehyde gases such as formaldehyde, etc. of low concentration on the order of ppb in a short response time, and that is strong in the bonding strength between organic adsorption film and substratum, excelling in durability, and that allows easily fixing of various organic adsorption layers to the substratum, providing many options of organic adsorption layer, and that allows combination of multiple types of organic adsorption layers, exhibiting response to a variety of gases and excelling in versatility. The gas detector (1) comprises substratum (2), surface treatment layer (3) with functional groups superimposed on the substratum (2) and organic adsorption layer (4) superimposed on the surface of the surface treatment layer (3).
