acetonitrile; air; albendazole; chemometrics; chloramphenicol; eggs; enrofloxacin; liquid chromatography; liquid-phase microextraction; methanol; methylene chloride; nicarbazin; pH; sodium phosphate; solidification; solvents; trimethoprim; veterinary drugs; zinc sulfate
Abstract:
... Two extraction strategies for albendazole, chloramphenicol, trimethoprim, enrofloxacin, oxitetracycline and nicarbazin in egg were optimized for its quantitation by liquid chromatography. First, two designs were built to find out the optimized condition for the air assisted-dispersive liquid-liquid microextraction based on solidification of organic drop: a fractional factorial and a central compos ...

Abstract:
... A sensitive, confirmatory ultra-high performance liquid chromatography–tandem mass spectrometric method was developed and validated to detect 23 veterinary drugs and metabolites (nitroimidazoles, benzimidazoles, and chloramphenicol components) in bovine milk. Compounds of interest were sequentially extracted from milk with acetonitrile and basified acetonitrile using sodium chloride to induce liqu ...
