| titleOfInvention | Hydride gas detection tape |
| abstract | (57) [Abstract] [Purpose] To provide a tape for detecting a hydride gas whose photosensitivity is lowered as much as possible while maintaining the original mechanical strength of a reagent carrier by a color reaction. . [Structure] A porous cellulose tape containing a gas adsorbent such as silica fine powder and a humectant such as glycerin between fibers, silver paratoluenesulfonate as a color reagent, and a light resistance enhancer. Then, it is impregnated with para-toluenesulfonic acid to prepare a detection tape. When the detection tape is exposed to the hydride gas in the sampling gas, silver p-toluenesulfonate is reduced by the hydride gas to form colloidal silver, and a reaction mark is produced. Since colloidal silver is produced in proportion to the gas concentration, the hydride gas concentration can be known by measuring the optical density of the reaction trace. The tape (A) using silver p-toluenesulfonate has a much lower photosensitivity than silver nitrate used in conventional tapes (B, C). No discoloration occurs after storage for a period of time. |
