NITRIC OXIDE DETECTOR ELEMENT

摘要

Provided is a nitric oxide detection element which is capable of measuring a trace amount of NO gas contained in a gas in a scale of several ppb and of which the time degradation in performance is suppressed. The nitric oxide detection element includes at a surface thereof: a dye having a porphyrin skeleton and containing divalent cobalt as a central metal; and a radical scavenger. The nitric oxide detection element includes a substrate 12 and a sensing film 11 formed on a surface of the substrate 12. The sensing film 11 may contain the dye and the radical scavenger.
