Simple and efficient method for the determination of fipronil and two main metabolites in eggs by capillary liquid chromatography.

Posted on 16 July, 2021 by fqm302

Capillary liquid chromatography (CLC) with UV-diode array detection has been proposed for the first time to determine fipronil and two metabolites, fipronil-sulfide and fipronil-sulfone in hen egg samples. Under optimum conditions, analytes eluted in less than 12 min. Despite the complexity … Continue reading →

Evaluation of a selective approach for the determination of 5-nitroimidazoles in aquaculture products by capillary liquid chromatography using molecularly imprinted solid-phase extraction

Posted on 6 November, 2017 by fqm302

Capillary liquid chromatography with UV detection is proposed for the determination of 5-nitroimidazole residues in aquaculture products. The separation was carried out in a C18 column at 20 °C, using a mobile phase consisting of water and acetonitrile, at 7 μL/min and … Continue reading →

Ion-paired extraction of cephalosporins in acetone prior to their analysis by capillary liquid chromatography in environmental water and meat samples

Posted on 2 August, 2013 by fqm302

Ion-pair extraction of cephalosporins from aqueous solution into acetone by the addition of ammonium sulfate to a 1:2 (v/v) acetone–water solvent was carried out followed by their determination using reversed-phase capillary liquid chromatography. The analytes included are cephoperazone, cefquinome, cephalexin, … Continue reading →
