Rapid 'on-site' methods are required by the pork industry to screen for the presence of antibiotic residues in meat and meat products. There are few rapid and easy-to-use methods suitable for application in non-analytical laboratories. This paper describes a novel approach for the screening of sulfamethazine in pork muscle using matrix solid phase dispersion, a microcolumn preconcentration step and thin-layer chromatographic detection. The characteristics of the method are reported allowing for the detection of residues at the maximum residue limit of 100 ppb. Results from the industrial evaluation of the complete method are also presented.
猪肉行业需要快速的“现场”方法来检测肉类和肉制品中抗生素残留的存在。适合在非分析实验室应用的快速且易于使用的方法很少。本文描述了一种使用基质固相分散、微柱预浓缩步骤和薄层色谱检测法来筛查猪肌肉中磺胺二甲嘧啶的新方法。报告了该方法的特性,能够检测出最大残留限量为100 ppb的残留物。还给出了完整方法的工业评估结果。
