摘要
采用超高效液相色谱串联质谱法(ultra performance liquid chromatography-tandem mass spectrometry,UPLC-MS/MS)分析办公用品和包装材料中染料的析出对水产品中结晶紫残留量检测的干扰。样品(黑色签字笔划线纸、黑色马克笔划线纸、蓝色圆珠笔划线纸、送样样品标签纸、激光打印标签纸、留样用塑料袋)用乙腈提取,采用UPLC-MS/MS测定。结果表明待测样品除黑色签字笔划线纸以外,均检出结晶紫残留,显性结晶紫和隐性结晶紫含量随时间的延长,均有不同程度的增加。蓝色圆珠笔划线纸、送样样品标签纸和激光打印标签纸中结晶紫检出值较高;黑色马克笔划线纸、留样用塑料袋中检出显性结晶紫。
Ultra-performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS)was used to analyze the interference of dye precipitation in stationery and packing materials on aquatic products gentian violet detection.Samples like black pen marking paper,black mark pen marking paper,blue ballpoint pen marking paper,labell paper,thermal labels and sample plastic bag were extracted with acetonitrile and analyzed by UPLC-MS/MS.The results showed that the residue of gentian violet was detected in all the samples except for the black marking paper.The contents of gentian violet and leuco gentian violet were increased in different degrees along with the extension of time.The gentian violet was higher in blue ballpoint pen marking paper,label paper and thermal labels.Gentian violet was detected in black marker pen marking paper and sample plastic bag.
