抄録

Particle formation by radiolysis was observed in the neutralizer of the differential mobility analyzer (DMA) in air or N₂ under presence of O₃ and/or SO₂. The effects of SO₂ concentration, relative humidity and O₃ concentration on the particle formation in the neutralizer were investigated. This particle formation may cause artifacts in aerosol size-measuring using a DMA. The particle number concentration increased with increasing of SO₂ concentration and relative humidity. In low humidity condition, remarkable increase of the number concentration was observed when 0.1 ppm of O₃ was added to SO₂ (0.2 ppm)/N₂ (H₂O < 15 ppm) mixture. The mechanisms of the particle formation in the neutralizer under presence of O₃ were discussed.
