Determination of veterinary drug residues in chicken meat using corona discharge ion mobility spectrometry

A positive corona discharge ion mobility spectrometry (CD-IMS) has been evaluated for the determination of three residual veterinary drugs including furazolidone (FUR), chloramphenicol (CAP), and enrofloxacin (ENR) in poultry for the first time. Pretreatment included extraction of the drugs from samples and further treatment of the extracts by solid phase extraction (SPE) using C-18 sorbents. The limits of quantification (LOQs) were less than 20 mu g kg(-1) for all compounds. The calibration plots for these compounds were linear to about three orders of magnitude. The validity of the method was demonstrated by the analysis of spiked and real samples. (c) 2006 Elsevier B.V. All rights reserved.
