Determination of clopidol residues in chicken tissues by liquid chromatography: collaborative study.
Eighteen laboratories participated in a collaborative study on the determination of clopidol residues in chicken muscle tissues by liquid chromatography. Of these, results from 16 laboratories which rigorously followed the method were subjected to statistical analysis. The method performance was assessed by all participants using 14 samples of chicken muscle fortified at concentrations ranging ...
متن کاملDetermination of tilmicosin residues in chicken, cattle, swine, and sheep tissues by liquid chromatography.
A method was developed and validated for determination and quantitation of tilmicosin residues in swine, cattle, and sheep edible tissues, as well as chicken fat, skin, and muscle over a concentration range of 0.025 microg/g-20 microg/g. For chicken kidney and liver, the method was validated over a range of 0.060 microg/g-20 microg/g. The tissue sample was extracted with methanol and a C18 cart...
متن کاملAnalytical Procedure for the Determination of Doxycycline Residues in Animal Tissues by Liquid Chromatography
A sensitive liquid chromatographic method for the determination of doxycycline in animal tissues has been prepared and validated. The extraction of the analyte from biological matrix was performed with the solution of oxalic acid and ethyl acetate. The samples were cleaned up by solid phase extraction (SPE) procedure using a carboxylic acid cartridge. Chromatographic separation was carried out ...
متن کاملDetermination of residual clopidol in chicken muscle by capillary gas chromatography-negative chemical ionization-mass spectrometry.
A selective, sensitive gas chromatography-mass spectrometry (GC-MS) method with negative chemical ionization (NCI) was developed for the detection and quantification of clopidol in chicken muscle. Chicken muscle samples were extracted with acetonitrile and concentrated to dryness; the residue was redissolved in ethyl acetate and applied to an Alumina B cartridge for cleanup. The residue was der...
متن کاملDisopyramide determination by gas chromatography, liquid chromatography, and gas chromatography--mass spectrometry.
Disopyramide is determined in serum by gas chromatography with a nitrogen-selective detector, by liquid chromatography, and by gas chromatography--mass spectrometry. Comparable results are obtained with the three techniques, with a within-run and between-run precision of 5 to 10% (coefficient of variation). Least-squares analysis of data on patients' sera, analyzed first by gas chromatography (...
