Beschreibung
Zusammenfassung:	Sensors, sensing systems and sensing methods of the invention provide for detection of peroxides, including for example, vapor-phase H2O2 and organic peroxides such as di-tert-buty\ peroxide. A sensor and sensing method of the invention uses at least two phthalocyanines, one of which exhibits an oxidation reaction with peroxides and the other of which exhibits a reduction reaction with peroxides. A peroxide is readily identified by a sensor of the invention when one of the at least two phthalocyanines exhibits increased resistance to current flow and the other of the at least two phthalocyanines exhibits decreased resistance to current flow. L'invention porte sur des capteurs, des systèmes et des procédés qui permettent de détecter des peroxydes, y compris des peroxydes H2O2 en phase vapeur et des peroxydes organiques tels qu'un peroxyde de di-tert-butyle. Le capteur et le procédé de détection de l'invention font appel à au moins deux phtalocyanines, dont l'une subit une réaction d'oxydation avec les peroxydes et l'autre, une réaction de réduction. Le capteur de l'invention permet de rapidement identifier un peroxyde lorsque l'une des deux phtalocyanines précitées présente une résistance augmentée au flux de courant et l'autre, une résistance amoindrie.
