Title:
NITRIC OXIDE DETECTOR ELEMENT
Document Type and Number:
WIPO Patent Application WO/2012/017604
Kind Code:
A1
Abstract:
There is provided a nitric oxide detector element capable of measuring traces of nitric oxide gas contained on the order of several parts per billion in a gas, wherein the nitric oxide detector element exhibits minimal degradation in performance over time. The nitric oxide detection element has, on a surface thereof, a pigment with a porphyrin skeleton and with divalent cobalt as a central metal thereof, as well as a radical scavenger. The nitric oxide detector element comprises a substrate (12) and a sensing film (11) formed on a surface of the substrate. The pigment and the radical scavenger may be included in the sensing film.
