General description

Florfenicol is a broad-spectrum amphenicol antibiotic used against diseases affecting domestic and wild animals.

Application

The analytical standard can be used as follows:
  • To measure florfenicol and its main metabolite florfenicol amine in tilapia meat by solid phase extraction (SPE) and ultra high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS)
  • Multi-residue analysis of three amfenicols in animal feed samples by HPLC-MS/MS method, following European Commission Decision 2002/657/EC(2)Determination of florfenicol in different animal feedstuff samples by thin layer chromatography (TLC) coupled with HPLC-UV detection
  • Residue analysis of florfenicol in broiler meat and liver samples by a reversed phase-HPLC method in combination with UV detection at 223 nm
  • Competitive indirect-chemiluminescent enzyme-linked immunosorbent assay (CL-ELISA) based quantitative analysis of florfenicol and its major metabolite florfenicol amine in chicken muscle samples, validated as per Commission Decision 2002/657/EC
