| 摘 要： | 根据SN/T 1768-2006、GB/T 19857-2005、GB/T 20361-2006标准,比较适合以上标准的3种水产品前处理方法,即:固相萃取法、旋转蒸发法、氮气吹干法.采用液相色谱串联质谱(LC-MS)检测水产品中孔雀石绿(MG)、结晶紫(CV)含量.以3种前处理方法所得回收率为指标,确定固相萃取法为适合的方法.换用不同的固相萃取小柱,对固相萃取法进行优化,以获得最大回收率.结果表明固相萃取小柱LH的最佳回收率超过88％,该固相小柱的重复使用回收率损失仅3％.该方法简便、快速、灵敏,适于水产品中孔雀石绿及其代谢物隐色孔雀石绿,结晶紫及其代谢物隐色结晶紫残留量的检测. |

| Abstract: | According to SN/T1768-2006,GB/T19857-2005,GB/T20361-2006 standard,to compare three different pre-treatment methods(solid phase extraction,rotary evaporation and nitrogen blow dry method) of aquatic products.Use Liquid chromatography tandem mass spectrometry to measuring contents of MG and CV in the sample.Change different solid-phase extraction column in pre-treatment to find the best column.The result showed that Solid Phase Extraction is the best determination way with higher recovery rate over 88%.Conclu... |
