Method for detecting residual quantity of methyl sulfamate

The invention provides a method for detecting residual quantity of methyl sulfamate, and belongs to the technical field of testing and analyzing materials by utilizing column chromatography. The method comprises the following steps: respectively preparing a derivatization reagent, an internal standard solution, a reference substance solution and a test solution, adding the derivatization reagent into a sample to be detected, heating and deriving to promote a target object to be converted into a detection target object, and then forming a stationary phase by cyanopropyl benzene and dimethyl siloxane for gradient elution. The method is applied to quantitative determination of methyl sulfamate trace residues, the detection sensitivity can reach 0.7468 ng/ml, the method has the advantages of being simple, sensitive, accurate, reliable, high in stability, good in reproducibility and the like, and the recovery rate is 95.01%-108.56%. 本申请提供一种氨基磺酸甲酯残留量的检测方法，属于利用柱色谱法测试分析材料技术领域。分别配置衍生试剂、内标溶液、对照品溶液和供试品溶液，向待测样中加入衍生试剂，加热衍
