Domestic large-sized ammonia synthesis plant, synthetic tower import and export process gas and recycle gas were divided into (H2, N2, NH3, AR, he) most of the advanced gas chromatography analysis, the analysis method of operation are roughly the same.
Tengzhou City Xiangying Analysis Technology Co., Ltd. R & D anti-corrosion patented special multidimensional XiangyingGC7990plus gas chromatograph, using two valve two column backflush cutting, first of all with column I will separated from the process gas for he + Ar + N2 and N H3 and other components, and by the switching valve, the He + Ar + N2 mixture into chromatographic column II were isolated, T C D detector. The external standard method was used to calculate the concentration of each component, reached a sample analysis of the whole group of the objective.
国内大型合成氨厂中，合成塔进出口工艺气与循环气全组分（Ｈ２、Ｎ２、ＮＨ３、Ａｒ、Ｈｅ）分析大都采用比较先进的气相色谱法，分析操作方法大致相同。
滕州市翔鹰分析技术有限公司研发出防腐专利专用多维XiangyingGC7990plus气相色谱仪，使用两阀两柱的切割反吹，首先用色谱柱Ⅰ将工艺气分离为 Ｈｅ ＋ Ａｒ ＋ Ｎ２ 与 Ｎ Ｈ３ 等组分，然后通过阀切换，将 Ｈｅ ＋ Ａｒ ＋ Ｎ２ 的混合气导入色谱柱Ⅱ进行分离，用 Ｔ Ｃ Ｄ 检测器检测，外标法计算出各组分浓度，达到一次进样全组分分析的目的。
