摘要： Purity certified reference materials (CRMs) as the basis for traceability chains are play an important part in chemical metrology. In the context of supporting the implementation of monitoring plan of national quality and safety for agro-products, a project for development of fluoroquinolones purity CRMs was launched. These CRMs aimed to use as benchmark to assure the comparable and traceable measurement results of fluoroquinolone antibiotic residues in nationwide monitoring laboratories. In characterization, certified values were assigned by using mass balance (MB) and quantitative nuclear magnetic resonance (qNMR). Homogeneity, stability and uncertainty evaluation were sufficiently studied. These fluoroquinolones purity CRMs including enrofloxacin (GBW(E)090817), ciprofloxacin (GBW(E)090818), norfloxacin (GBW09251), fleroxacin (GBW09249), lomefloxacin hydrochloride (GBW09250), ofloxacin (GBW(E)090822), danofloxacin mesylate (GBW(E)100475), sarafloxacin hydrochloride (GBW(E)0900960), pefloxacin mesylate (GBW09256) can be used to ensure the accurate and reliable measurement results acquired in the mandatory routine monitoring by providing a metrological traceability source for establishing comparability.
