Application

Mixture of methanol with 0.1% trifluoroacetic acid and water with 0.1% trifluoroacetic acid was used as the mobile phase in the HPLC apparatus, used for the quantification of eight quinolones (danofloxacin, oxolinic acid, flumequine, enrofloxacin, ciprofloxacin, sarafloxacin, difloxacin and marbofloxacin) in bovine muscle, milk and aquacultured products.
