Název v původním jazyce

Speciation of Se forms by IC-ICP-MS method in food and pharmaceutical materials

Popis výsledku v původním jazyce

Arsenic, chromium, tin, selenium, and similar elements are well known as toxic elements or biogenic,that can occur in foodstuffs in several forms. These forms have for humans’ different toxicity or other biological activity therefore determination of total amount of these elements in the foodstuffs given insufficient information. In the framework of this work was created a procedure for the determination and speciation of mentioned elemental compounds in food samples like canned beverages, fish, and other vegetable foods. The procedure involved the use of high-performance liquid and ion chromatography (HPLC, IC) method and detection by atomic fluorescence spectrometry with hydride generation technique (HG-AFS). As a comparison method was used mass spectrometry method with inductive coupled plasma (ICP-MS) for the determination of total elemental content.Separation of organically bounded tin compounds was performed by HPLC on a column of ACE C-18, 3 µm, 15 cm Ö 1.0 mm with off-line detection by ETA-AAS. All of the above forms of tin compounds can be separated with this column. Due to the improvement in the detection of organically bounded tin, HPLC with identical ACE C-18 column coupled online with ICP-MS or spectrofluorimetric could be recommended. Similar or better results can be achieved by using ion chromatography (IC) with Ion Pac AC7 columns in combination with ICP-MS (IC-ICP-MS).
