The development of a laboratory system to investigate the interactions of tropospheric aerosol and HOx radicals

This thesis describes the development and application of a laboratory system to investigate the loss of peroxy radicals to aerosol. The laboratory system consisted of an aerosol flow tube coupled to a custom-built PEroxy Radical Chemical Amplifier (PERCA). Aerosol was generated using an atomiser and t...
