Sensitivity of MIS Capacitors with Palladium Electrode to Aromatic Nitro Compounds Vapor
Abstract
The temperature and time modes of the high-energy aromatic nitro compound vapor pyrolysis have been studied. The optimal conditions for reliable concentration measurement of gas-phase decomposition products of nitro compound molecules using MIS capacitors based on palladium-dielectric-silicon structures were determined. It has been established that the sensitivity of MIS sensors to nitroaromatic compound vapor appears when a gaseous sample is exposed to a temperature of 400°C and reaches a maximum at 500 – 550°C with an average duration of vapor heating of 1 s.
