Polluting Particles: Direct Analysis of Organic Aerosol via PTR-TOFMS
Fig. 4 Charon PTR-TOFMS mass spectrum containing around 1000 chemical compositions of organic particulate species (top panel), the time series of selected traces including total organics, condensed PAHs and lubricant oil (middle panel) and the particle size resolved particle concentration as measured by a scanning mobility particle sizer (SMPS). Patched grey areas labeled HEPA and VOC indicate periods of HEPA particle-phase background and direct gas-phase measurements, respectively.
