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

2-Year Study of Chemical Composition of Bulk Deposition in a South China Coastal City: Comparison with East Asian Cities

“…The procedures for analytical measurements have been described previously (11), and the quality assurance procedures included the routine running of blanks and control samples as well as replicate samples. Briefly, the measurement of pH utilized a Ross combination pH semimicro electrode, with ionic strength adjustor added to triplicate portions of the samples.…”

“…The procedures for analytical measurements have been described previously (11), and the quality assurance procedures included the routine running of blanks and control as the ratio of the equivalent concentrations of total anions to total cations was in the range from 0.77 to 1.21 for all of the samples. However, an even higher (1.00 ( 0.15) standard was adopted herein, so that 156 samples (i.e.…”

Recent advances and trends in capillary electrophoresis of inorganic ions

“…Environmental analysis is an application field where CE has been continuing to attract the most interest in the past few years. Several extensive studies were undertaken to demonstrate the capablities of CE for the monitoring of major inorganic anions and cations from environmental waters, such as waters of river and lake systems, groundwaters from pits and contaminated waters from turf production areas [175], from bulk/dry deposition and aerosol [176] or size-classified ice crystal samples [177,178]. The use of CE has been shown to provide the sample throughput, accuracy and precision required for routine analyses of ionic components from these samples in the mM-nM ranges, with sufficient speed, very low sample consumption, and the possibility of in-field use.…”

Recent advances in capillary electrophoresis and capillary electrochromatography of pollutants

“…Some recent applications are summarized in Table 1 [69,99,[142][143][144][145][146][147][148][149][150][151][152]. Determination of perchlorate in groundwater [143]; inorganic anions at trace levels in snow [144]; silicate with other nutrients in river water [145]; cationic and anionic species in cleanroom wipers [147], environmental water samples [148], and size-classified ice crystals [150]; inorganic anions in microbial fermentation [146]; trace metal cations in rain water [69]; and low molecular mass (LMW) mono-and dicarboxylic acids in airborne and vehicle-emitted samples [99,100,142] has been successfully performed and validated with the results obtained by other methods or using laboratory-made reference samples.…”

“…5). Fung and Tung [152] employed a newly developed Tam et al [149] described a simple protocol for collection of bulk dry deposition on a daily basis, and for sizeselected aerosol sampling. The soluble components of these samples were analyzed by CE, which has been shown to provide the sample throughput, accuracy and precision required for routine analysis in the mM-mM ranges with very low sample consumption.…”
