TI  - Second organic aerosol formation from the ozonolysis of alpha-pinene in the 
      presence of dry submicron ammonium sulfate aerosol.
PG  - 1183-8
AB  - An indoor chamber facility is described for investigation of atmospheric aerosol 
      chemistry. Two sets of alpha-pinene ozonolysis experiments were conducted in the 
      presence of dry ammonium sulfate seed particle: ozone limited experiments and 
      a-pinene limited experiments. The concentration of gas phase and particle phase 
      species was monitored continuously by on-line instruments and recorded 
      automatically by data sampling system. The evolution of size distribution was 
      measured by a scanning mobility particle sizer (SMPS), and alpha-pinene consumed 
      was measured using GC-FID. Secondary organic aerosol (SOA) produced for seed-free 
      system is 100% organic in content, resulting from a sufficient supersaturation of 
      low volatility organics to produce homogeneous nucleation followed by 
      condensation to the aerosol. Secondary organic aerosol produced in seeded system 
      is a mixture of organic and inorganic constituents, initially forms via 
      condensation onto the inorganic particles, and subsequent growth occurs via 
      absorption into the organic surface coating the inorganic core. Although the 
      formation process and the size distribution for seed-free system and seeded 
      system is different, the ultimate mass of SOA formed is equal, and SOA yield for 
      the two system located in the same regression line when using one-product model, 
      suggesting that the presence of dry ammonium sulfate seed has no measurable 
      effect on the total aerosol yield, and the dry seed particle acts solely as a 
      site upon which organic deposition occurs.
