摘要: A simple, rapid, and sensitive method for the determination confirmation of aminoglycosides streptomycin, dihydrostreptomycin, spectinomycin, apramycin, kanamycin, paromomycin, gentamicin neomycin in cow’s milk as well bovine porcine muscle kidney was developed. Validation performed on basis an in-house concept with different factor-level combinations accordance Commission Decision 2002/657/EC. After extraction trichloroacetic acid solution, clean-up by way SPE. LC-MS/MS analysis carried out means HILIC column separation analytes, using MS/MS positive ESI mode to measure transitions substances MRM mode. For quantification, matrix calibration curves linear range around MRLs internal standard tobramycin were used. The calculated validation parameters like CCα, CCβ, recovery (94–103%), relative repeatability RSDr (3.6–9.7%), within-laboratory reproducib...
