“…Literature based on europium-sensitized fluorescence methods for tetracycline determination in milk is more scarce (Savage et al 1998;Gala et al 1997), and it includes only a few examples of solid-matrix time-resolved luminescence and stopped flow techniques; only recently has the method received renewed attention (Chen and Liu 2004;Traviesa-Alvarez et al 2007). …”

The development of a fast and reliable screening method for the determination of tetracycline residues in milk is described and compared to high-performance liquid chromatography. The method is based on europium-sensitized luminescence: The emissive properties of the lanthanide cation are used as a fingerprint of europium (III) complexation with tetracycline. The optimization of the extraction and purification procedures provided a simple and convenient route to prepare stable tetracycline samples that can safely resist freezing cycles. The method is validated for the first time in milk matrix: The results show that accuracy and precision of the method meet complaints with the criteria of the Commission Decision 2002/657/EC. The proposed method has a false compliant rate (β error) lower than 5%.

SummaryThe potential of a non-aqueous, capillary electrophoresis (NACE) system for separating oxytetracycline from three of its impurities -tetracycline, 4-epioxytetracycline and 4-epitetracycline -using UV detection has been studied. The running bufferwas: 25 mM sodium acetate, 1 mM EDTA, methanesu Ironic acid, pH 4, dissolved in MeOH- ACN (50:50, v/v). The method was also used to determine these compounds in pig plasma. A solid-phase extraction (SPE) procedure as a clean-up step has also developed. For this we tested Sep Pak Cl8, LiChrolut EN and OASIS cartridges. OASIS cartridges were best. Recoveries were 90 -100% for all compounds except EOTC which had a recovery of 74%.
