Determination of Strobane Residues in Meat and Meat Products by Gel Permeation Chromatography Coupled with Gas Chromatography-Negative Chemical Ionization Mass Spectrometry
A method for the analysis of strobane residues in meat,beef,mutton,chicken,chinese bacon and dry pork was developed using gas chromatography-negative chemical ionization mass spectrometry(GC-NCI/MS),based on gel permeation chromatography(GPC) purification.The homogenized sample was extracted with n hexane,then cleaned by GPC with ethyl acetate-cyclohexane solution(1∶1) as mobile phase.The targeted compounds were detected under selected ion monitoring(SIM)mode and quantified by the external standard method.The high correlation coefficents(r=0.999 7)of strobane were obtained within a concentration range of 0.01-2.0 mg/L .The LOQ of strobane was 10 μg/kg.In the six matrixes mentioned above,the average recoveries of strobane at spiked concentration of 10.0-50.0 μg/kg ranged from 80% to 98%,with RSDs(n=8) of 2.1%-8.7%.This method was suitable for the identification and quantification of strobane residues in various meat and meat products.
