Inorganic species analysis by CE – An overview for 2007–2008

Abstract

This review article represents the sixth in a series of reviews on CE applied to inorganic analysis, appearing in this journal, and focuses on material published in 2007-2008. As a fundamental review, it examines primarily those documents in which the emphasis is on advances in general CE methodology which are traditionally set on the attainment of higher detection sensitivity and greater preconcentration factors both in capillary and microchip separation formats. Following a major research trend of the previous review period (see A.R. Timerbaev, Electrophoresis 2007, 28, 3420-3425), publications focusing on the quantification of different element species continue to rapidly outpace other applications. A range of practicable separation and detection designs tailor-made to species-selective analysis are critically discussed in order to assess their impact on the rate of development and wide acceptance of CE in the field.

Inorganic analysis using CE: Advanced methodologies to face old challenges

“…This title section has been long a healthy element of our biennial review work on CE of inorganic species . However, in the latest account we have noted a decline in the development of new detector designs for conventional CE.…”

Capillary and Microchip Electrophoresis

“…Thus, complex formation is often used for separation and monitoring is typically effected by indirect photometric (Fig. 7) or conductivity detection [113][114][115][116]. Examples presented in Figure 17 depict the separation of anions (Fig.…”

“…Both capillary and microchip based instrumentation can be employed. Other detection principles for inorganic ions, including inductively coupled plasma MS and amperometry, are being used in research laboratories [116,118]. There is a wide range of fields of applications in which CE is or is becoming a popular method for analysis of inorganic ions and small molecules, including environmental analysis (also in the field with a portable CE instrument) [116,119], food analysis [120], as well as clinical and forensic analysis [121,122].…”
