Short summary
We present the development of a high-resolution time-of-flight chemical ionization mass spectrometer (HR-ToF-CIMS) method, utilizing protonated ethanol as reagent ions to simultaneously detect atmospheric gaseous amines (C1 to C6) and amides (C1 to C6). Deployment of this ethanol HR-ToF-CIMS has been demonstrated in a field campaign in urban Shanghai, China, detecting amines (from a few pptv to hundreds of pptv) and amides (from tens of pptv to a few ppbv).
