高效液相色谱柱后衍生荧光检测体系测定生果、蔬菜

宣布日期：2016-06-30 点击次数： 63678

[摘要]总体目标：创立并考察了用优质色谱仪离子交换柱后发展荧光在线查测组织体制校正生果、蔬果中氨基甲酸酯类化肥使用量的在线查测体例；体例：以乙腈为拆分有机溶剂，拆分液颠末滤、兑水后，容忍固相提取传统手工艺和男朋友分手、水污染，淋洗液经兑水后，进行带荧光在线查测器和柱后发展组织体制的优质色谱仪色谱停下在线查测。以抹去当时明确，外标法定量分析分析量。效果：该体例不光滑收受收回率是72.91％～114.96％，RSD为1.094％～1.377％，在线查测限(S／N=3)为 0.001~0.01mg.L-1；论述：试表明该体例对生果、蔬果中氨基甲酸酯类化肥使用量的在线查测效果保持不变、重新性好，可以于其明确定量分析阐发。
如需具体化原材料，请约见雇主办事效率期间：800-9993-800\400-7102-888。
