摘要
对现有的Trace 1310气相色谱仪进行改造,加装镍转化炉、氢火焰离子化检测器(FID),以及分子筛柱替换脱氧柱,建立了一点校正法,一次进样不受前后进样温度和压力的影响,完成工业氢中O_(2)+Ar、N_(2)、CO、CO_(2)、CH_(4)的检测,其相对标准偏差为3.21%~4.92%、加标回收率为97.60%~100.79%,操作简便、分析速度快,为公司回用高盐废水深度治理装置制氢或者新购工业氢提供了品质判定依据。
The existing Trace 1310 gas chromatograph was remoulded by adding a nickel reformer,flame ionization detector(FID)and a molecular sieve column to replace the deoxidization column,in order to set up one point correction method.The point correction method is used to analyze trace impurity gases such as O_(2)+Ar,N_(2),CO,CO_(2)and CH_(4)in industrial hydrogen,having the advantage of a sample injection which is not affected by the temperature and pressure before and after the injection.The relative standard deviation and recovery rate were 3.21%~4.92%and 97.60%~100.79%seperatively by this simple method.It provides the basis for the quality judgment of hydrogen production or newly purchased industrial hydrogen in the high-salt wastewater advanced treatment unit of our company,which the operation is simple and the analysis speed is fast.
