We present a Chemical Ionisation Quadrupole Mass Spectrometer (CI-QMS) with a novel discharge ion source. In addition to the expected detection of PAN, peracetic acid and ClNO〈sub〉2〈/sub〉, the instrument is also sensitive to SO〈sub〉2〈/sub〉, HCl and acetic acid through ion chemistry unique for our ion source. We present ionisation schemes along with illustrative data sets from field campaigns underlining the potential of the CI-QMS as an alternative to polonium, especially for application in the marine boundary layer.
