Karsa MION direct field observations shed light on heterogeneous processes on marine aerosol

Karsa multi-scheme chemical ionization inlet (MION) was deployed during an intensive measurement campaign at Mace Head atmospheric research station in Ireland. In this study published in the prestigious Proceedings of the National Academy of Sciences of the United States of AmericaMION was at the core of the bromide-based chemical ionization atmospheric pressure interface time-of-flight mass spectrometer (Br-CI-APi-TOF). MION enabled a team lead by scientist from INAR/University of Helsinki and Tampere University to measure HOI, ICl, and IBr simultaneously with high resolution. Limits of detection (LOD) were determined to be 3-5 times lower than earlier studies at 0.09, 0.15, 0.08, and 0.07 pptv (1 min-average, 3σ) for HOI, ICl, IBr, and I2, respectively.Karsa is proud that five of the authors of the study are co-founders, and demonstrate how Karsa’s products and people support ground breaking research.
