Researchers at the University of Toronto, Canada, have evaluated the Ambient Ion Monitor-Ion Chromatograph (AIM-IC) system’s performance and accuracy for the measurement of the water-soluble chemical composition of atmospheric fine particulate matter (PM2.5).
The team, led by Jennifer Murphy, determined the system’s detection limits for gas phase NH3(g), SO2(g), and HNO3(g) and particle phase NH4+, SO42−, and NO3−. The group also evaluated the system for response time to changing compound concentrations, with a variety of different membranes.
