“…The performance of FASI in terms of precision and accuracy was reported to be comparable to GC or LC methods, or even better [22,31,32]. However, because of its operational mechanism, namely, stacking being under-2480 W. Liu Ref.…”

“…In general, detection limits with UV-Vis detection are relatively poor and can be improved by sample preconcentration methods, such as SPE on C 18 [20] or sample stacking as used by Carro-Diaz et al [25].…”

CE methods for the speciation of inorganic and organomercury compounds are reviewed. Sample preparation, separation conditions and detection modes are discussed. Efficient separation and sensitive determination of mercury species by CE typically involves complexation with various thiols, chromogenic and other chelating agents; however, some methods do not require complexation. Spectrophotometric detection based on UV-visible absorption is by far the most commonly used. Hyphenated techniques, such as CE/inductively coupled plasma (ICP)-MS, hydride generation coupled to ICP-MS or atomic fluorescence spectrometry and CE/atomic absorption spectrometry are gaining popularity due to their high sensitivity and selectivity. Last, but not least, the potential and applications of electrochemical methods for detection of separated mercury species are outlined.

“…Medina et al [22] speciated inorganic and organomercury species. Furthermore, an improvement of mercury speciation was carried out by Carro-Diag et al [23] using sample stacking as the injection technique. The method was tested using different reference materials with a certified methylmercury content.…”

Metal ion speciation and capillary electrophoresis: Application in the new millennium

2005

View full text Add to dashboard Cite

Metal ions are essential for human beings at low concentrations but they are toxic or even carcinogenic at high concentrations. Many metallic ions are found in the environment in different species which are differentiated not only by their physicochemical forms but also by their diverse toxicities with respect to living organisms (speciation). CE has been used for metal ion speciation. The present review article describes the recent trends in metal ion speciation by CE. This article deals with the speciation of metal ions, optimization of the speciation (by independent and dependent variables), hyphenation of CE, validation of the methods, mechanisms of speciation, CE versus chromatography and conclusions.
