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
