Speciation of inorganic selenium using capillary electrophoresis–inductively coupled plasma-atomic emission spectrometry with on-line hydride generation

Speciation of magnesium in rat plasma using capillary electrophoresis‐inductively coupled plasma‐atomic emission spectrometry

“…Coupling CE to ICP spectrometry, which is a powerful method for metal speciation, further broadens the range of CE applications [45][46][47][48][49][50][51][52]. CE-ICP combines the advantages of the high-resolution separation of CE and the highly sensitive and element-selective detection of ICP spectrometry [47].…”

Inorganic selenium speciation in environmental samples using selective electrodeposition coupled with electrothermal atomic absorption spectrometry

“…Separation techniques for elemental speciation can be generally classified into chromatographic and non-chromatographic techniques. The chromatographic techniques include high performance liquid chromatography [9], capillary electrophoresis [10], size exclusion chromatography (SEC) [11] and ion-chromatography [12]. Non-chromatographic separation techniques include solvent extraction [13], co-precipitation [14], cloud point extraction [15] and solid phase extraction (SPE) [16][17][18][19][20][21][22][23].…”

“…Because of the disadvantages of conventional extraction techniques, solvent-free sample preparation methods or those employing fewer organic solvents are becoming increasingly important. Combinations of general separation methods with various detection techniques such as X-ray absorption spectrometry [24][25][26], neutron activation analysis (NAA) [27][28][29], inductively coupled plasma optical emission spectrometry (ICP-OES) [10,[30][31][32] and inductively coupled plasmamass spectrometry (ICP-MS) [8,33], have been applied to measure trace selenium and its species in various samples. Although a high sensitivity is reported for these methods, they are very expensive and unavailable in many academic labs.…”

Application of alkaline mode electrochemical hydride generation for the detection of As and Sb using atomic fluorescence spectrometry

“…As a sample introduction technique, chemical hydride generation (CHG) based on the reaction between sodium tetrahydroborate (or potassium tetrahydroborate) and an analyte in acidic solution has been widely used in atomic absorption spectrometry (AAS) [1], atomic fluorescence spectrometry (AFS) [2], mass spectrometry (MS) [3] and inductively coupled plasma atomic emission spectrometry (ICP-AES) [4]. EcHG has been proposed as a valid alternative to CHG [5].…”
