Abstract 2) originating from the oxidation of VOCs. The measurement of HOMs is made by a NO3 - 2 SO4). The instrument response to HOMs is typically estimated using H2 SO4, as HOMs are neither commercially available nor easily synthesized in the laboratory. The resulting calibration factor is then applied to quantify all species detected using this technique. In this study, we explore the sensitivity of the instrument to commercially available small organic compounds, primarily dicarboxylic acids, given the limitations associated with producing known amounts of HOMs for calibration. We compare these single-compound calibration factors to the one obtained for H2 SO4 under identical operational conditions. The study found that the sensitivity of the NO3 - 3 - chemical-ionization mass spectrometer (CIMS), for example, HOMs.
