Short summary

A novel configuration of the Aerodyne high resolution time-of-flight chemical ionization mass spectrometer (HR-TOF-CIMS) as a switchable reagent ion (SRI) HR-TOF-CIMS is presented and described along with data collected at the Southern Oxidant and Aerosol Study (SOAS) during the summer of 2013. Formic acid and other relevant species are presented, and they exhibit a strong diel cycle being rapidly produced during the day and dropping below the limit of detection at night.
