Short summary
We present the first application of this online and offline strategy using the new extractive electrospray ionization time-of-flight mass spectrometer (EESI-TOF), which achieves increased chemical specificity relative to other online techniques. Measurement and source apportionment of 1 year of filter samples collected in Zurich, Switzerland, show seasonal contributions from fresh and aged wood combustion in winter and biogenic emission-derived SOA in summer, as well as other sources.
