“…In the case of lighter metals, such as calcium and magnesium, ICP‐atomic emission spectroscopy (AES) presents as before a compatible choice for element‐specific detection. This was confirmed by quantitative characterization of their speciation in red blood cells 126 and rat plasma 127, respectively. The molecular mass of some of eight Ca‐containing species found by CE‐ICP‐AES in the former sample was estimated after it was subjected to ultrasonic dialysis 126.…”

A further effort to hyphenate CE with electrothermal atomic‐absorption spectrometry for the goal of mercury biospeciation analysis should be mentioned, as this hyphenation was for the first time realized through a cold‐vapor generation interface 128.…”

This article is the seventh in a series examining biannually the methodological developments in the field of CE analysis of inorganic species and covers relevant documents published between January 2009 and December 2010. Following an analysis of the significant accomplishments that have impacted the field in two recent years, a survey of advances in general CE methodology is presented. Subsequently, several notable trends that can be perceived in this well-established field are discussed: the continuing rise of ME and consequent development of suitable detection techniques, most notably contactless conductivity detection, the constant pace of advances in speciation analysis, and an increase in non-analytical CE applications to study complexation and (bio)transformation reactions of metal analytes. A range of recently emerged multi-detection designs, ICP-MS interface devices, and separation systems, for which outpacing work has been conducted, are also brought into focus.

“…Furthermore, the arsenic bioaccessibility in shrimp was not increased with the addition of ascorbic acid or fruit juices. An ultrasonic dialysis and capillary electrophoresis system with detection by ICP-OES was developed for the identification and determination of calcium species in human red blood cells [108]. Ultrasound dialysis enhances the movement of liquids and facilitates mass transfer which results in rapid equilibrium.…”

During the last few years, various flow-based separation/preconcentration methodologies have gained pertinent novel advances and exhibited powerful capability in the field of sample pretreatment and their hyphenation with detection by atomic spectrometry. The present mini-review presents and discusses the progress of flow-based sample processing approaches commonly used for the assay of trace elemental species with detection by atomic spectrometry, including preliminary sample pretreatment, solid phase extraction (including solid phase microextraction), liquid-liquid extraction, vapor generation and dialysis techniques. Special emphasis has been paid on the novel applications and analytical procedures hyphenated with atomic spectrometry. The future perspectives of flow-based sample pretreatment protocols in the determination of trace elements and their speciation are also discussed.

“…To study Al metabolism and the effectiveness of chelation treatments, a rapid procedure for speciation was developed by Murko et al 103 using a HiTrap desalting size exclusion column, with ICP-MS to show the elution profile. Free Ca 2+ and eight Ca-containing species with Mr ranging from <15 kDa to >100 kDa were identified in human erythrocytes following ultrasonic-assisted dialysis and separation by CE-ICP-MS. 104 Iodinated X-ray contrast agents were separated using TLC. In this work, by Meerman et al 54 an extraction device coupled the thin layer plate to an ICP-mass spectrometer (section3.2).…”

Amid the traditional development and applications work reported during the period covered by this review, the most obvious identifiable trend is that of downsizing. This is seen with techniques requiring smaller sample sizes or more effective analyte pre-concentration, and with new instrumentation. Procedures for extraction included the use of nanoparticles in various ways and the single-drop methodology with one example exploiting 1-dodecanol, a material that shifts between liquid and
