“…However, 48.61-59.12 mg/l were found in Southern Brazilian Merlot wines (Dutra et al 2010). The concentration levels of Ca in our study were close to the values found in other researches (Ough et al 1982;Anjos et al 2003;Álvarez et al 2007;Rodríguez et al 2011;Du et al 2012;Şen & Tokatli 2014). Since the mean calcium content in wine is 80 mg/l, it can result in tartrate instability in wine.…”

Değİrmencİ Karataş D., Aydin F., Aydin I., Karataş H. (2015): Elemental composition of red wines in Southeast Turkey. Czech J. Food Sci., 33: 228-236.Mineral profiles of wines and soil extracts were analysed in the five most popular international wines (Cabernet Sauvignon, Syrah, Merlot, Cot, and Tannat) and national Boğazkere, which is one of the highest-quality grapevine varieties grown in Turkey. We carried out study to establish the mineral and metal concentrations in wines from Southeast Anatolia of Turkey. The ICP-OES method was used for accurate determination of concentrations of 12 elements including Ca, Cd, Co, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, and Zn. The high levels of iron, potassium, sodium, and calcium were observed in the wine samples analysed. Major elements were also abundantly found in the soil samples. Minor element contents of wine samples were compatible with results other researches. The amount of metal content in wine is an important issue. A remarkable finding of the study was that heavy metals like Pb (found below acceptable limits only in three samples), Co, and Cd were not detected. The results obtained did not exceed the maximum acceptable limits established by the Office International de la Vigne et du Vin. Our results showed that the mineral compositions of wine and soils were interrelated. The analysis of the soil samples taken from the vineyard locations showed similar results for highest composition of major minerals. The characteristics of the wines produced in the Southeast Region of Turkey were analysed for the first time.

“…In this table, the results given for Canadian wines (second column) are from Okanagan Valley and Niagara Peninsula [4]. The elemental concentration ranges for Brazilian wines [15] are given in the fifth column of Table 1. When compared, it can be seen that the iron and copper quantities are more or less in the same level for various wines, except for the last column where copper and zinc quantities are much larger [6] than the others.…”

“…Nickel is present in wines owing to the use of nickel containing stainless steel containers for wine fermentation and storage in modern cellar technology. There are only a few data in the literature [15,18] for the determination of nickel in wine. The nickel content in Brazil wine [15] was changing between 20 and 300 lg L -1 .…”

A new and simple differential pulse polarographic method for the analysis of wine has been established. With this method, it was possible to determine simultaneously six trace elements in wine. There was no need for time consuming extraction and separation procedures with danger of contamination. The polarogram of wet digested wine was taken initially in pH 2 acetate buffer and Pb, Cd, and Zn were determined by standard additions. Ethylene diamine tetraacetic acid (EDTA) was added and pH was increased to six by addition of NaOH. Fe and Cu were determined subsequently. The ammonia buffer, pH 9.5, was identified as the best medium for separation and determination of Ni and Zn. The quantities of trace elements were found as Cu 290 ± 20 lg L -1 , Fe 8960 ± 50 lg L -1 , Pb 148 ± 17 lg L -1 , Cd 16 ± 8 lg L -1 , Zn 460 ± 25 lg L -1 , and Ni 78 ± 17 lg L -1 .

The use of synchrotron radiation (SR) as an excitation source for total reflection X-ray fluorescence analysis (TXRF) offers several advantages over X-ray tube excitation. Detection limits in the fg range can be achieved with efficient excitation for low Z as well as high Z elements due to the features of synchrotron radiation and in particular the high brilliance in a wide spectral range and the linear polarization in the orbital plane. SR-TXRF is especially interesting for samples where only small sample masses are available. Lowest detection limits are typically achieved using multilayer monochromators since they exhibit a bandwidth of about 0.01 DE/E. Monochromators with smaller bandwidth like perfect crystals, reduce the intensity, but allow X-ray absorption spectroscopy (XAS) measurements in fluorescence mode for speciation and chemical characterisation at trace levels. SR-TXRF is performed at various synchrotron radiation facilities. An historical overview is presented and recent setups and applications as well as some critical aspects are reviewed.
