COLORING MATTER SENSOR AND RECORDING SET

摘要

PROBLEM TO BE SOLVED: To detect an organic molecule gas with high sensitivity. SOLUTION: The coloring matter sensor for detecting an organic gas being a Bronsted base contains a polymer having a strong acidic group (a), and the cationic organic coloring matter (c) which is bonded to the polymer and loaded with protons by the strong acidic group so that the molar ratio (c/a) of the cationic organic coloring matter (c) and the strong acidic group (a) is 1/10-1/25.
