Short summary

Gas phase organosulfur compounds in air serve as precursors of particles which impact human health, visibility, and climate. We compare here two different approaches to measuring these compounds, one an online mass spectrometry technique and the other canister sampling followed by offline analysis by gas chromatography. We show that each approach has its own advantages and limitations in measuring these compounds in complex mixtures, including some artifacts due to reactions on surfaces.
