浩瀚气相色谱仪测定液氧中二氧化碳GC7990

For the use of acid-base titration method for the determination of carbon dioxide content in liquid oxygen deficiency GJB2040-94 "standard" provisions of the settlement of liquid oxygen in the Tengzhou Xiangying Analysis Technology Co. Ltd by GC7990 gas chromatography, T column, using nickel catalyst to convert carbon dioxide into methane with hydrogen flame detector. And the precision of the method can reach 2.1%, the determination by chromatography with the provisions of the national military standard method results in good consistency. Method to convert carbon dioxide into methane by gas chromatography hydrogen flame detector, can be completed on the carbon dioxide content in liquid oxygen testing method is reliable, simple and easy.
为解决GJB2040-94《液氧规范》中规定的用酸碱滴定法测定液氧中二氧化碳含量存在的不足,滕州市翔鹰分析技术有限公司采用GC7990气相色谱法,T填充柱,用镍触媒将二氧化碳转化为甲烷后用氢火焰检测器检测。,方法的精密度可达到2.1%,用色谱法测定的结果与用国军标规定的方法测定的结果一致性好。将二氧化碳转化为甲烷后用色谱法氢火焰检测器检测的方法,可以完成对液氧中二氧化碳含量的化验,方法可靠,简便易行。
