•    Air quality monitoring is an important challenge due to health, economic and societal issues
•    Innovative analytical method with negative and positive SIFT-MS instrument
•    Understanding of ion-molecule reactions including the air permanent components
•    Simultaneous and high frequency monitoring of VOC, CO2, O3, O2 and water


Selected Ion Flow Tube–Mass Spectrometry (SIFT-MS) with both positive (H3O+, O2●+ and NO+) and negative precursor ions (O●−, OH, O2●−, NO2 and NO3) was successfully used for the
