Determination of Lead and Strontium Isotope Ratios in Wines by Inductively Coupled Plasma Mass Spectrometry
Thirteen wine assortments from Romania were investigated from the point of view of their metal content and isotopic ratios Pb/Pb and Sr/Sr. The determination was performed by ICP-QMS. The aim of this study was to detect and quantitatively determine the toxic metals in some white and red wine samples and to investigate them from the point of view of isotopic ratios Pb/Pb and Sr/Sr. Six metals wi...
متن کاملIsotope ratio analysis of lead in blood and environmental samples by multi-collector inductively coupled plasma mass spectrometry.
It is widely recognized that lead (Pb) affects children's cognitive function, even at relatively low blood lead levels (<10 µg dL(-1)). The determination of the source of Pb in children is essential for effective risk management. The use of multi-collector ICPMS (MC-ICPMS) for isotope ratio measurements of Pb in environmental and biological samples was examined for this purpose. MC-ICPMS with a...
متن کاملPrecise determination of element/calcium ratios in calcareous samples using sector field inductively coupled plasma mass spectrometry.
A new method was developed for rapid and precise simultaneous determination of Mg/Ca, Sr/Ca, Mn/Ca, Cd/Ca, Ba/Ca and U/Ca ratios in foraminiferal shells using sector field inductively coupled plasma mass spectrometry (ICPMS). Element/calcium ratios were determined directly from intensity ratios using external, matrix-matched standard to correct for instrumental mass discrimination. Because of l...
متن کاملImproved measurement of iodine in food samples using inductively coupled plasma isotope dilution mass spectrometry.
A new ICP-MS method for the determination of iodine in food samples is presented. The method makes use of a new miniature cyclonic spray chamber and a concentric glass nebulizer that is designed for low sample uptakes and is operated in a self-aspirating mode. As a consequence the wash-out was accelerated over conventional systems. This configuration allows the direct determination of iodine in...
