摘要:

建立了用超高效液相-串联质谱仪检测猪肉中种磺胺多残留的方法。采用乙腈提取,正己烷去脂,碱性氧化铝柱净化后,用超高效液相-串联质谱仪进行定性及定量分析。方法最低检出限为0.25 μg/kg。方法灵敏、准确,可实现多种磺胺激素同时进行定性及定量分析。

Abstract:

A ultra performance liquid chromatography-tandem mass spectrometric (UPLC/MS/MS) method was developed for simultaneous determination of 13 sulfonamides in the porcine meat. Components were extracted from homogenized sample with acetonitrile, defatted by n-hexane and further extracted by Alumia B. The limit of determination (LOD) was 0.25 μg/kg. The method was proved to be satisfactory in precision, securacy and sensitivity for multiresidues determination.

Key words: sulfonamide, residues analysis, ultra performance liquid chromatographytandem mass spectrometry
