Název v původním jazyce

Enhancing the efficiency of chemical vapor generation of zinc in a multimode sample introduction system

Popis výsledku v původním jazyce

Chemical vapor generation (CVG) of Zn was carried out in a multimode sample introduction system (MSIS) and coupled to inductively coupled plasma mass spectrometry (ICP-MS) for detection. CVG conditions were studied and 0.4% (m/v) 8-hydroxyquinoline as the reaction modifier in 0.08 mol dm-3 H2SO4 and 3.0% NaBH4 in 0.1 mol dm-3 NaOH were found optimal, providing the limits of detection and quantification of 2.8 ng cm-3 and 9.3 ng cm-3, respectively. The overall CVG efficiency of 5.3 +/- 0.1% was determined from comparison with solution nebulization-ICP-MS, while 5.7 +/- 0.1% was determined using 65Zn radiotracer and radiometry. The developed methodology was verified by determination of Zn in the standard reference material of fresh water (NIST 1643f). Interference study conducted with 13 hydride-forming and transition elements did not prove ability of any of the tested element to further increase the CVG efficiency, but at the same time, none of them exhibited serious interference except Ag.
