“…A previous extraction step is usually employed to avoid matrix effects, such as solid-phase microextraction with divinylbenzeneecarboxenepolydimethylsiloxane fibres (Rial-Otero, Yagüe-Ruiz, Cancho-Grande, & Simal-G andara, 2002), liquideliquid extraction (Vaquero-Fern andez et al, 2008), solid-phase extraction with Oasis HLB cartridges (Fontana, Rodríguez, Ramil, Altamirano, & Cela, 2011), dispersive liquideliquid microextraction (Rodríguez-Cabo, Rodríguez, Ramil, & Cela, 2011), or the QuEChERS (quick, easy, cheap, effective, rugged, and safe) procedure (Moeder, Bauer, Popp, van Pinxteren, & Reemtsma, 2012;Walorczyk, Drozdzynski, & Gnusowski, 2011). Also, immunoassays have been developed and validated in wines for the analysis of pesticides like benalaxyl (Rosso, Giraudi, Gamberini, Baggiani, & Vanni, 2000), tebufenozide (Irwin, Tolhurst, Jackson, & Gale, 2003), fenhexamid (Mercader & Abad-Fuentes, 2009), or bromopropylate (Ramon-Azc on, S anchez-Baeza, Sanvicens, & Marco, 2009), showing excellent performance.…”
