Atmospheric Analysis Facility: Trace Gases and Aerosols

The purpose of the Atmospheric Analysis Facility for TGAs is to analyse air samples to measure concentrations and fluxes of pollutants, including: (1) inorganic reactive trace gases (NH3, HNO3, SO2, HCl, HONO); (2) aerosol chemical components (NH4+, NO3-, SO2=, Cl-, Na+, K+, Ca++, Mg++); and (3) volatile organic compounds. These analyses support UK air monitoring networks (AGANET, NAMN), compliance monitoring and research projects.
