Arsenic speciation in fish was performed using isocratic elution with cation exchange column high-performance liquid chromatography and inductively coupled plasma-mass spectrometry detection. The separation of arsenobetaine and dimethylarsinic acid was performed in 12 min. DOLT-4 dogfish liver and NIST RM-50 albacore tuna certified reference materials were used to evaluate the accuracy for the determination of total arsenic in fish. In addition, reference materials were analyzed for arsenobetaine and dimeth...

Selenium is one of the trace and essential elements for good health but required only in a very narrow range. Hence, determination of selenium in trace level is important. In this work, cloud point extraction (CPE) with non-ionic surfactant Triton X-114 and the fluorometric ligand, 2,3-diaminonaphtalene (DAN) were used for extraction of trace amounts of organic and inorganic selenium species prior to their determination by spectrofluorometry. CPE parameters affecting complexation and phase separation were o...
Speciation of Selenium in Supplements by High Performance Liquid Chromatography-Inductively Coupled Plasma-Mass Spectrometry

Anion and cation exchange high-performance liquid chromatography (HPLC) combined with inductively coupled plasma-mass spectrometry (ICP-MS) were used for speciation of selenium in supplements. All the parameters in the extraction, separation, and determination procedures were optimized. Recovery studies for the selenium species from the anion and cation exchange columns were performed and there were no analyte losses. Limits of detection for selenium(IV), selenium(VI), Se in selenomethionine, and Se in sele...
