Use of capillary electrophoresis in the analysis of aerosol and bulk/dry deposition collected on a daily basis

Simple protocol is described for the collection of bulk and of dry deposition on a daily basis, and for size-selected aerosol sampling. The use of capillary electrophoresis (CE) as the instrumental method of analysis provides the sample throughput, accuracy and precision required for routine analyses of ionic components from these samples in the µeq.dm-3neq.dm-3 ranges, with very low sample consumption. The scheme presented enables the simultaneous analyses of inorganic anions and organic acids, as well as of major cations. Representative results are presented for samples collected in Hong Kong.
