Color indicator composition and film for detecting hydrogen peroxide
摘要:
In a multilayer analysis film for detecting hydrogen peroxide by dry process which comprises a support and a reagent layer having contained therein a color indicator composition comprising peroxidase and a substance capable of causing a optically detectable change in the presence of hydrogen peroxide and peroxidase, the color indicator composition is characterized by further containing specific pyrogallol derivatives. Such pyrogallol derivatives improve stability during storage of such a multilayer analysis film.
