“…It should be highlighted that this founding was not previously obtained by other researchers in analysis of wine samples after dilution or digestion and analyte detection by ICP OES (Gonzálvez et al 2008;Grindlay et al 2008). In contrast, R 2 was <0.9 for concentrations <10 mg L −1 were lower; however, the results were still positively correlated.…”

“…The process of digestion destroys organic wine components (ethanol, organic acids, polysaccharides), which leads to reduce their influence on analyte transport efficiency and plasma thermal conditions during analysis by ICP OES technique (Grindlay et al 2008;Moreno et al 2008). Similarly as in the case of sample dilution, all the 15 elements were measured in the obtained extracts of wine (Figs.…”

In the present study, an inductively coupled plasma optical emission spectrometer ICPE-9820 with the mini-torch technology that significantly reduces the consumption of plasma gas to 7.0 L min respectively). The recoveries were between 88.2 and 110 %, 65.9 and 106 %, and 62.8 and 109 %, whereas the relative standard deviations (RSDs) varied between 0.04 and 4.62 %, 0.74 and 5.57 %, and 0.70 and 5.80 %, respectively, for the procedure of sample dilution, microwave digestion, and water bath digestion.

“…These solutions represent the matrices obtained after 5-fold and 10-fold wine dilution with high purity water, respectively (i.e. the most widely employed dilution factors reported in the literature to reduce non-spectral interferences when dealing with elemental analysis of wine [6,8,22]); and (iii) a 7% w w -1 nitric acid solution plus 200 mg L -1 of K, 10 mg L -1 of Ca and of Mg, and 2 mg L -1 of Na.

AbstractThis work explores the multi-element capabilities of inductively coupled plasma -mass spectrometry with collision/reaction cell technology (CCT-ICP-MS) for the simultaneous determination of both spectrally interfered and non-interfered nuclides in wine samples using a single set of experimental conditions. The influence of the cell gas type (i.e. He, He + H 2 and He + NH 3 ), cell gas flow rate and sample pre-treatment (i.e. water dilution or acid digestion) on the background-equivalent concentration (BEC) of several nuclides covering the mass range from 7 to 238 u has been studied. Results obtained in this work show that, operating the collision/reaction cell with a compromise cell gas flow rate (i.e. 4 mL min -1 ) improves BEC values for interfered nuclides without a significant effect on the BECs for non-interfered nuclides, with the exception of the light elements Li and Be. Among the different cell gas mixtures tested, the use of He or He + H 2 is preferred over He + NH 3 because NH 3 generates new spectral interferences.2 No significant influence of the sample pre-treatment methodology (i.e. dilution or digestion) on the multi-element capabilities of CCT-ICP-MS in the context of simultaneous analysis of interfered and non-interfered nuclides was observed.Nonetheless, sample dilution should be kept at minimum to ensure that light nuclides (e.g. Li and Be) could be quantified in wine. Finally, a direct 5-fold aqueous dilution is recommended for the simultaneous trace and ultra-trace determination of spectrally interfered and non-interfered elements in wine by means of CCT-ICP-MS. The use of the CCT is mandatory for interference-free ultra-trace determination of Ti and Cr. Only Be could not be determined when using the CCT due to a deteriorated limit of detection when compared to conventional ICP-MS.
