Isopropyl Alcohol Volatile Sensor Development for In-Flight Air Quality

Abstract

Breathing air quality within commercial airline cabins has come under increased scrutiny due to the identification of volatile organic compounds from the engine bleed air used to provide oxygen to cabins. Here, we chose isopropyl alcohol (IPA), a main component of de-icer spray, engine exhaust, and cleaning solvents for breathing lines and life support gear used in the aerospace community, as a target analyte. Given the presence of IPA and the risk of cognitive effect in pilots/passengers, there is a need to real-time monitor the concentration of in-flight and breathing-line IPA This work developed and validated an IPA selective gas sensor that can distinguish the target molecule from other volatile organic compounds such as acetone or isoprene in real time.
