胶粘剂中三苯的测定

采用气相色谱内标法测定胶粘剂中苯、甲苯、二甲苯的含量,选择环己酮作为内标物、FID检测器、以氮气为载气,选择合适的柱温、检测器温度、汽化温度,合适的气流比、分流比等。解决此方法中一些常见的问题,建立一套完整的检测方案。

A method has been developed for separation and determination of benzene, toluene, and xylene .The adoption spirit mutually the color table inside mark method measurement the glue in the content of the benzene, methyl benzene, xylene, choose the personal 酮 of wreath conduct and actions inside mark thing, detector of FID, with nitrogen spirit in order to carry the spirit, choose fit pillar, detector temperature, fit current of air compare, repesition of redundant personnel than etc., resolve this method in some familiar problem, build up a set of integrity of examination project.
