Feasibility of the PILS-IC-VA online system was demonstrated by collecting aerosol samples in Herisau Switzerland, at defined time intervals; air pollution events were simulated by burning lead- and cadmium-coated sparklers.
The PILS-IC-VA setup is straightforward and allows semi-continuous measurements of water-soluble aerosol ionic components at 60 min intervals. PILS-IC-VA is an indispensable tool to monitor rapid changes in aerosol particle ionic composition, caused, for example, by brief smoke plume impacts, that would be impossible to detect with filter methods. PILS-IC-VA is an invaluable contribution for investigating the composition, transport, and evolution of atmospheric aerosols. The system is highly suited for long-term unattended field use in remote regions.
