title: Sensitive liquid chromatographic--mass spectrometric assay for norfloxacin in poultry tissue.
abstract: A highly sensitive and specific method for the determination of norfloxacin in poultry tissues by LC-MS was developed and validated. An extract of the sample was separated on a C(18) reversed-phase column and analyzed by LC-MS. The mobile phase was gradiently flowed with 2% acetic acid and acetonitrile. The limit of detection and limit of quantitation were 1 and 5 ng/g, respectively. Mean recoveries from various spiked tissues were 87.2% (ranging from 82.5 to 92.7%) for norfloxacin. The method has been successfully applied to determine norfloxacin in poultry muscle.
