An on-column fluorometric derivatization method was developed for the determination of histamine and 1-methylhistamine (HMs) by high-performance liquid chromatography. The system for the derivatization consisted only of a commercially available single-plunger pump and a reversed-phase C18 column supported on synthetic polymer with a mobile phase of(More)
A simple and rapid high-performance liquid chromatographic (HPLC) method for the simultaneous determination of sulphamonomethoxine (SMMX), sulphadimethoxine (SDMX), sulphisozole (SIZ), nalidixic acid (NA), oxolinic acid (OXA), piromidic acid (PMA), furazolidone (FZ) and sodium nifurstyrenate (NFSA) in cultured fish was developed. The drugs were extracted(More)
A simple and rapid method using high-performance liquid chromatography (HPLC) for the determination of mirosamicin in animal tissues has been developed. The drug was extracted with 0.3% metaphosphoric acid-methanol (7:3, v/v), and the extracts were cleaned on a Bond Elut SCX (500 mg) cartridge. The HPLC separation was performed on a Puresil 5C18 column (150(More)
A simple, rapid and reliable high-performance liquid chromatographic (HPLC) method for the simultaneous determination of residual fluoroquinolones (benofloxacin, danofloxacin, enrofloxacin and ofloxacin) in chicken has been developed. The drugs were extracted with 0.2% metaphosphoric acid-acetonitrile (7:3, v/v), followed by a Bond Elut C18 clean-up(More)
A simple and selective method for the determination of sulphamethazine (SMT) and its metabolite, N4-acetylsulphamethazine (N4-AcSMT), in meat by high-performance liquid chromatography (HPLC) with photodiode-array detection was developed. The drugs were extracted from meat with 0.2% metaphosphoric acid-methanol (6:4), followed by a Bond-Elut C18 clean-up(More)
