摘要: Abstract A quantitative multiresidue method covering more than 100 veterinary drugs, belonging to different drug families, has been developed. The proposed approach uses an liquid–liquid–solid extraction technique (bi-polarity extraction) which is capable in recovering polar, medium polar and apolar compounds. thorough generic reversed phase solid-phase (SPE) clean-up removes interfering proteins provides clean stable extracts. Dedicated rinsing steps are reduce analyte adsorption on glass walls precipitating proteins. resulting extract analyzed by ultra-performance liquid chromatography (UPLC) coupled time of flight mass spectrometry (TOF). was validated according the Commission Decision 2002/657/EEC. Validation coved relevant meat matrices (muscle, kidney liver).
