A New Aerosol Sampler for Time-resolved PAH and Anion Analysis

M. Crooks, A. Zerrath, A. Eiguren-Fernandez, S. Hering

A new quantitative sampling system has been developed to collect sequential time-resolved, dry aerosol particles from PM2.5 down to 5 nm in diameter. The size of the deposition area allows reducing collection times by increasing the concentration of particles in the 50-100 ┬Ál volume of solvent used to extract the chemicals of interest. Results from field measurement campaigns show hourly concentrations of selected ions and 12 hour trends for several PAHs.
