Investigation of Secondary Organic Aerosol Formation in the Hydrocarbon/Da Reaction: Implementation of APCI/MS as an Analytical On-Line Technique A contribution to subprojects CMD and AEROSOL B Warscheid and T Hoffmann Institutfur Spektrochemie und angewandte Spektroskopie (ISAS), Bunsen-Kirchhoff-Str. 11, 44139 Dortmund, Germany Introduction The atmospheric fate of terpenes is strongly influenced by ozone generated loss processes in the troposphere (Hoffmann et al, 1997). Products formed in the reaction of biogenic volatile organic compounds (VOCs) with ozone are characterised by their low volatility. Therefore, gas-to-particle conversion of these compounds represents an important pathway for the formation of secondary organic aerosol (SOA) (Andreae and Crutzen, 1997; Zhang et al, 1992). A series of investigations are focussed on the determination of the reaction rate constants (At
