名称:毛细管柱
规格:30m*0.32mm*0.25um
型号:HH-5
应用:GB 31656.17-2022 食品an全guo家标准 水产品中二硫氰基甲烷残留量的测定 气相色谱法
浩瀚色谱(山东)应用技术开发有限公司建立了气相色谱-脉冲火焰光度法(GC-PFPD)测定水产品中二硫氰基甲烷(MBT)残留的分析方法.用二氯甲烷-正己烷溶液(1:1,v/v)在超声条件下提取水产品中的MBT,然后用中性氧化铝固相萃取小柱对提取物进行净化和富集,通过HH-5石英毛细管柱(30m×0.32mm×0.25μm)分离,后采用配有脉冲火焰光度检测器的气相色谱仪进行测定,外标法定量.MBT在1.0-20.0mg/L范围内线性关系良好,相关系数为0.9971;检出限为0.1mg/kg;加标回收率为65.6%-97.6%,精密度为6.32%-12.8%(n=7).该法能满足水产品中药物残留检测的需求.
