(JA) ホルムアルデヒド検知センサ、および、それを用いたシステム
Abstract:
(EN) [Problem] To provide a formaldehyde detecting sensor capable of constantly monitoring formaldehyde selectively and with high accuracy. [Solution] This formaldehyde detecting sensor is provided with: a reaction portion which contains at least a hydroxylamine salt and which reacts with formaldehyde to generate an acid; and a response unit provided with an electrode supporting a carbon material having an electrical resistance which varies depending on the acid generated by the reaction portion. The hydroxylamine salt and the carbon material are separated from one another.
(FR) [Problème] Fournir un capteur de détection de formaldéhyde permettant de surveiller constamment le formaldéhyde de façon sélective et avec une grande précision. [Solution] La présente invention concerne un capteur de détection de formaldéhyde qui est pourvu de : une partie de réaction qui contient au moins un sel d’hydroxylamine et qui réagit avec le formaldéhyde pour générer un acide ; et une unité de réponse pourvue d’une électrode soutenant un matériau carboné ayant une résistance électrique qui varie en fonction de l’acide généré par la partie de réaction. Le sel d'hydroxylamine et le matériau carboné sont séparés l'un de l'autre.
(JA) 【課題】ホルムアルデヒドを選択的かつ高精度に、常にモニタリング可能なホルムアルデヒド検知センサを提供すること。 【解決手段】本発明によるホルムアルデヒド検知センサは、少なくともヒドロキシルアミン塩類を含有し、ホルムアルデヒドと反応し、酸を発生させる反応部と、反応部で発生した酸によって電気抵抗値が変化する炭素材料を担持した電極を備える応答部とを備え、ヒドロキシルアミン塩類と炭素材料とは離間している。
