名称：安捷伦7890B玻璃柱
规格：2m*1/4，80-100目
型号：1.5%OV-17+2%QF-1/Chromosorb AW DMCS（80-100目）
编号：20220818001
温度：240°C
应用：GB/T 5009.19-2003 食品中六六六、滴滴涕残留量的测定
六六六(BHC)、滴滴涕(DDT)都是以苯为原料合成的中等du性有机氯类农药,这两种农药化学性质稳定,在常温下蒸汽压很低不易挥发,gao温、日光或酸性条件下都很难分解.我国在1993年就已通告淘汰了这两种药剂,但由于它们都有高残留特性,现在我国蔬菜、水果等食品中仍将它们列入监测项目.
浩瀚色谱（山东）应用技术开发有限公司建立同时测定蔬菜、水果、茶叶、食用植物油等食品中六六六、滴滴涕的方法。方法:先用有机溶剂将食品中六六六、滴滴涕和三氯杀螨醇等残留物提取出来,再经磺化后采用气相色谱法测定。结果:该方法能很好地将4种六六六异构体、4种滴滴涕异构体和三氯杀螨醇分离开,三氯杀螨醇的加标回收率在84.0%~95.0%,相对测量不确定度小于10%,zui低检出量为0.01 ng。结论:该方法能同时测定食品中六六六、滴滴涕和三氯杀螨醇残留量。

Application: GB/T 5009.19-2003 Determination of 666 and DDT residues in food
666 (BHC) and DDT (DDT) are medium-duty organochlorine pesticides synthesized from benzene. These two pesticides have stable chemical properties, low vapor pressure at room temperature, and are not easily volatile. It is difficult to decompose under acidic conditions. my country has announced the elimination of these two agents in 1993, but because they have high residue characteristics, they are still included in monitoring items in vegetables, fruits and other foods in my country.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a method for the simultaneous determination of 666 and DDT in vegetables, fruits, tea, edible vegetable oils and other foods. Methods: The residues of hexahexahexanol, DDT and dicofol in food were first extracted with organic solvent, and then sulfonated and determined by gas chromatography. Results: The method could well separate four hexahexahexahexaisomers, four DDT isomers and dicofol. The recovery rate of dicofol was between 84.0% and 95.0%, and the relative measurement uncertainty was less than 10%. , the minimum detection amount was 0.01 ng. Conclusion: This method can simultaneously determine the residues of hexahexahexanol, DDT and dicofol in food.
