Abstract
Atmospheric aerosol samples, collected over the Pacific with various sampler types, were analyzed by PIXE, instrumental neutron activation analysis (INAA), ion chromatography (IC) and atomic emission spectrometry (AES), and the results were intercompared. The effects of sample storage were investigated by reanalyzing some samples by PIXE two years after the first PIXE bombardment. The various intercomparisons showed generally quite satisfactory agreement, implying that the analytical procedures used yield accurate concentration data. Some problems showed up for the halogens Cl and Br, but these are largely attributable to artifacts during sampling and storage.
