“…The composition of wines from the Canary Islands has been established, important differences of mean content being observed among the wines from the different islands which has permitted their differentiation according to their geographic origin (Barbaste, Medina, Sarabia, Ortiz, & Pérez-Trujillo, 2002;Díaz, Conde, Estévez, Pérez Olivero, & Pérez-Trujillo, 2003;Frías, Conde, Rodríguez Bencomo, García, & Pérez-Trujillo, 2003;Pérez Trujillo, Barbaste, & Medina, 2003).…”

“…In fact, it is necessary to dilute or decompose the wine because of the possible matrix interferences. Elements Al, Cd, Cu, Fe, Ni, Pb, and Zn could be determined without dilution, while elements Ca, K, Mg, and Na are analyzed after dilution of wine sample with water (Frias et al 2001;Frias et al 2003;Diaz et al 2003). Decomposition could be performed by wet digestion on a hot plate or in a microwave oven using concentrated HNO 3 , HClO 4 , and H 2 SO 4 or mixtures of these acids (Frias et al 2001;Frias et al 2003;Diaz et al 2003;Castiñeira Gómez et al 2004;Álvarez et al 2007;Ivanova-Petropulos et al 2013, 2015b.…”

“…2 Para isso têm sido utilizados métodos espectroscópicos de massa, 3 de emissão óptica, 4 de espectroscopia NIR 5 e de absorção atômica em chama. 6 No entanto, a técnica analítica padrão de referência utilizada para a verificação da autenticidade de vinhos no Brasil é a cromatografia. 7 Tal técnica apresenta um custo elevado de seus instrumentos e de manutenção constante, bem como requer a preparação de reagentes e soluções padrão com produção de resíduos prejudiciais à saúde e/ou ao meio ambiente, além de apresentar uma baixa frequência analítica.…”
