“…As can be seen from the table, the large majority of studies showed no comparison data. For the few that did, the comparison has been mainly between CZE and IC [3,23,25,41,43,45,63,65,67,70,72,74,76,77,84,86,96,97,104,106,110,111,113,119,124,126,127,131,134,135,140,141,146,148,149,152,158,174,190,194,195,219]. Typical examples include studies by Yang et al [126], who found that results obtained using a high-sensitivity method developed using sample stacking technique together with the use of an internal standard correlated well with a standard IC method, and work by Fung and Lau [149], who examined a CZE method for the analysis of inorganic anions in rainwater and used an IC technique in parallel, reporting that the results for the major anions were within statistical variation.…”

“…Accuracy can be achieved in one of two ways, firstly, through direct reference to a known standard, such as a quality control standard or certified reference material, or secondly, through reference to a standard analyzed using an alternative technique that is known to be accurate [218]. 110,111,113,119,124,126,127,131,134,135,140,141,146,148,149,152,158,174,190,194,195,219].

Despite the availability of commercial capillary electrophoresis systems for over ten years, where quantitative analysis is required, capillary zone electrophoresis (CZE) has often failed to replace ion chromatography as the method of choice for a large number of analytes, not least inorganic anions. To investigate the reasons for this apparent failing, a review is presented of work that has been carried out to-date involving the quantitative application of CZE to the determination of inorganic anions in industrial and environmental samples. This review summarizes work both investigating and improving the quantitative aspects of the CZE of inorganic anions. A complete survey of how CZE has been applied to the determination of inorganic anions in real samples is given, including what, if any, analytical performance parameters were investigated and quoted, and if quality assurance data and validation methods were briefly considered, thoroughly investigated or simply ignored.

Much research continues on improving speciation measurements in real-world samples, with advanced CE procedures tailor-made to the analysis of natural [94,95,156,157,160,161,168,173,187,249,250] and waste waters [79,94,95], soil solutions or extracts [78,104], air [253], minerals [245], industrial samples and technological solutions [83,189,190,198,233,235,236,254,256], pharmaceutical preparations [199,248,255], biological material [102,118,175,231,251,252], food [224], and animal feed [211], etc. In particular, an innovative methodology for the automatic monitoring of mercury species in aquatic samples was suggested by Valcárcel's group [237].…”

This review as a sequel of three earlier similar reports gives a summary of the progress and significant methodological developments, starting from 2002, in the use of capillary electrophoresis (CE) for inorganic ion analysis. As substantiated by the illustrative number of relevant references, improvements in sensitivity achieved both in and outside a CE system, advances in manipulating the separation selectivity, novel hardware configurations, and system performance innovations are continually being reported over the review period. Specifically viewed are the recent advancements in elemental (bio)speciation analysis, which remains one of the most fertile areas of CE research, as well as in three recently booming research topics: contactless conductivity detection, separations on microchips, and transient isotachophoretic preconcentration. A state-of-the-art picture of technique's potentialities within the field of interest presented here demonstrates that CE has become recognized and is growing in acceptance as a reliable alternative to traditional analytical methods such as high-performance liquid chromatography (HPLC).

Passive sampling and/or extraction techniques in environmental analysis: a review

et al. 2004

The current state-of-the-art of passive sampling and/or extraction methods for long-term monitoring of pollutants in different environmental compartments is discussed in this review. Passive dosimeters that have been successfully used to monitor organic and inorganic contaminants in air, water, sediments, and soil are presented. The application of new approaches to the determination of pollutants at the sampling stage is discussed. The main milestones in the development of passive techniques for sampling and/or extraction of analytes, and in biomonitors used in environmental analysis, are summarized in this review. Passive samplers and biomonitors are compared.
