摘要:

研究鲤鱼鱼肉基质中氟苯尼考的标准样品制备方法。通过添加氟苯尼考养殖鲤鱼获得样品基质,用液相色谱串联质谱法对样品的均匀性和稳定性进行检测,通过8 家实验室协作定值的方式对标准样品进行定值和不确定度评估,结果表明样品的均匀性良好,稳定性可达36 个月,可以用于水产品中氟苯尼考残留检测质量控制和相关的科研需要。

关键词: 标准样品, 氟苯尼考, 均匀性, 稳定性, 不确定度

Abstract:

A method for preparing florfenicol reference material (RM) from the muscle of common carp fish exposed to
aqueous florfenicol when alive was investigated. The homogeneity and stability of the prepared sample were detected
by liquid chromatography-tandem mass spectrometry. The certified value for florfenicol was based on analysis of results
obtained in 8 accredited laboratories and uncertainty evaluation was conducted. The results showed that the reference
material had a good homogeneity and stability within 36 months, and could be used for the determination of florfenicol
residue in aquatic products.

Key words: reference material, florfenicol, homogeneity, stability, uncertainty
