摘要
使用两阀两柱的气相色谱仪法，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。
Analyzes the process gases with two valves and two columns gas chromatography First separate ammonia from mixed gases(He+Ar+N 2) by column I,then pass the mixed gas(H e+Ar+N 2) through the valve and enter column Ⅱ to be separated,analyze those gases with TCD and at last calculate the concentration of each component with external standard method, fulfilling the total composition anlysis by once sample injecting
