Airborne measurement of inorganic ionic components of fine aerosol particles using the particle-into-liquid sampler coupled to ion chromatography technique during ACE-Asia and TRACE-P

[1] Eight inorganic ions in fine aerosol particles (Dp < 1.3 mm) were measured on board the NCAR C130 and NASA P-3B aircraft during the 2001 Aerosol Characterization Experiment (ACE)-Asia and the Transport and Chemical Evolution over the Pacific (TRACE-P) experiments, respectively. Concentrations of NH4 , SO4 2 , NO3 , Ca, K, Mg, Na, and Cl were determined using a particle-into-liquid sampler coupled to ion chromatography (PILS-IC) technique at a 4-min resolution and a limit of detection <0.05 mg m . The maximum total ion concentrations observed on the C130 and the P-3B were 27 mg m 3 and 84 mg m , respectively. During ACE-Asia, NH4 + and SO4 2
