“…Although this technology has been available for more than 10 years, the use of CCT for elemental analysis of wine has been scarce until recently [15][16][17]. The common strategy is based on the use of different sets of conditions for determining spectrally interfered and non-interfered elements, respectively.…”

“…Finally, it is also worth to mention that contradictory conclusions as to the optimum ICP-MS conditions for the determination of some elements can be found in the literature. For instance, determination of Mn, Ni, Zn, Sr, Mo, Cd, Ba and Pb has been carried out using either conventional ICP-MS [15] or CCT-ICP-MS [16,17].…”

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.

“…In Argentina, different chemometric procedures have been applied in order to establish quality criteria, genuineness and geographical and varietal differentiation in wine (Fabani, Arrúa, Vázquez, Diaz, Baroni & Wunderlin, 2010;Bentlin, Pulati, Dressler, & Pozebon, 2011;Di Paola-Naranjo et al, 2011;Fanzone et al, 2012), but none of them have applied the spectroscopy methods mentioned above.…”

This work discusses the determination of the provenance of commercial Torrontés wines from different Argentinean provinces (Mendoza, San Juan, Salta and Rio Negro) by the use of UV-vis spectroscopy and chemometric techniques. In order to find classification models, wines (n = 80) were analyzed using UV-Vis region of the electromagnetic spectrum. Principal component analysis (PCA), linear discriminant analysis (LDA) and partial least squares discriminant analysis (PLS-DA) were used to classify Torrontés wines according to their geographical origin. Classification rates obtained were highly satisfactory. The PLS-DA and LDA calibration models showed that 100% of the Mendoza, San Juan, Salta and Rio Negro Torrontés wine samples had been correctly classified. These results demonstrate the potential use of UV spectroscopy with chemometric data analysis as a method to classify Torrontés wines according to their geographical origin, a procedure which requires low-cost equipment and short-time analysis in comparison with other techniques.
