Abstract

Real time and long-term monitoring of aerosol chemical species is the subject of great scientific concerns and numerous technological developments. The Aerodyne Aerosol Chemical Speciation monitor (ACSM) has been developed for this purpose. It is currently operational at over 60 monitoring stations worldwide, with almost half of them being located in Europe (notably within the Aerosols, Clouds, and Trace gases Research InfraStructure). Understanding the reponse of these instruments to different chemical species and quantifying any possible artefacts is essential if we are to use these measurements for comparative studies and for model evaluation and development. A few recent studies have illustrated such possible measurement artefacts, notably at the mz44 peak (Crenn et al, 2015, Frohlich et al, 2015). The related variability in instrument response has been linked to an artefact response to inorganic aerosol (Pieber et al.,2016), however more recent work has illustrated that this response is dependent on aerosol mixing state (Freney et al., 2019). Here, we present results of laboratory experiments where the mz44 artefact was evaluated for various inorganic and organic mixtures, and a co-located measurement campaign in ambient air...
