Fig. 2: The normalized mass spectrum of secondary organic aerosol (SOA) factors.
From: Unraveling secondary organic aerosol formation from isoprene and toluene mixture
Normalized factor mass spectra of the isoprene- (F-ISO-1, F-ISO-2), toluene- (F-TOL-1, F-TOL-2) and mixture-related (F-MIX) SOA factors with four different m/z ranges in colors (≤50: red; 50–100: cyan; 100–150: green, and >150: deep blue). For readability, the signals in the corresponding m/z ranges were scaled by one, five, fifty, and five hundred times.
