New Criteria

В условиях повышенной конкуренции и обеспечения должной защиты потребителя от различных фальсификаций предложен эффективный метод контроля качества винодельческой продукции на основе элементного состава с использованием масс-спектрометрии с индуктивно-связанной плазмой. Предложены наиболее значимые элементы, характеризующие качество столовых вин и их соотношения и позволяющие разработать новые критериальные оценки качества и подлинности виноматериалов и вин. In the conditions of increased competition and ensuring proper protection of the consumer from various falsifications, an effective method of quality control of wine products based on the elemental composition using inductively coupled plasma mass spectrometry is proposed. The most significant elements that characterize the quality of table wines and their ratios are proposed, which are fundamental in the course of research, and allow us to develop new criteria for assessing the quality and authenticity of wine materials.

Plasma Mass Spectrometry

The pre-smolt stage of the scale of adult Norwegian Atlantic salmon from four populations, encompassing both farmed and wild hatchery stocks, has been analyzed by laser ablation inductively coupled plasma mass spectrometry (LA-HR-ICP-MS). The purpose of this study was to test for differences in elemental composition between stocks of Atlantic salmon that have lived in separate fresh water locations until the smoltification and natural run out or transportation to the sea-cages. The populations studied were from fish farms located at Bremanger and Sørfold, a cultivated stock from Mossa, and one wild local stock from the river Gaula. The following elements were included in the analytical protocol: Li, Mg, Ca, Cr, Mn, Fe, Zn, Sr, Ba, Pb, and U. Calcium was used as a natural internal standard. Classification of the analytical data is studied by multivariate statistical techniques such as principal component analysis (PCA). We have been able to delineate the population of Atlantic salmon ( Salmo salar L.) from Gaula and Mossa from the Bremanger and the Sørfold stock based on the ten elements analyzed. The Bremanger and Sørfold stocks were partially delineated. The differences in elemental composition in the scales, which makes the delineating of the four stocks possible, probably reflects geological differences in the bedrock at the four fresh water locations experienced by the salmon during the pre-smolt stage.

Fish Otoliths

The elemental composition of fish otoliths is of considerable interest to those who wish to reconstruct temperature, migration, or environmental histories of individual fish based on assays of the otolith growth sequence. However, reported differences in otolith elemental composition among studies may be due in part to performance differences among four of the most popular instruments for targeted elemental analysis: wavelength-dispersive electron microprobe (WD-EM), energy-dispersive electron microprobe (ED-EM), proton-induced X-ray emission (PIXE), and laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS). To rigorously compare the sensitivity, accuracy, and precision of these four analytical tools, the International Otolith Composition Experiment distributed blind-labelled real and artificial otoliths of known but varied elemental composition to eight laboratories for assay of 10 selected elements. No one instrument type was sensitive to each element, nor was any one instrument preferred for use in all assays. In general however, abundant elements such as Na and K could only be measured accurately with an electron microprobe, while the trace elements required PIXE or LA-ICPMS. Strontium could be measured with considerable accuracy and precision by WD-EM, PIXE, and LA-ICPMS. The presence of significant, and occasionally large, differences among laboratories suggests that comparisons among published studies should be made cautiously and only after appropriate calibration.
