浩瀚气体中微量氨的测定气相色谱仪GC7990

Tengzhou Xiangying Analytical Technology Co., Ltd. developed a rapid gas chromatographic method for the determination of trace ammonia in gas. The method mainly solves the difficulty of detecting ammonia in the presence of ammonia in the raw gas of the existing gas chromatograph, which is less than 1000ppm. A rapid chromatographic method for the determination of trace. By using the following steps in sequence: (1) The sample gas is introduced into the sampling line and the sample loop through a vacuum pump. (2) Carrier gas The gas in the sample loop is brought to the chromatographic system, and the ammonia in the sample gas is separated from the other components by the pre-separation column and the analytical column.
滕州市翔鹰分析技术有限公司研发一种气体中微量氨的快速气相色谱分析方法，主要解决现有气相色谱技术存在的NO原料气中氨含量低于1000ppm时氨的检测困难问题，提出了一种微量氨的快速色谱分析方法。通过依次采用以下步骤：(1)样品气通过真空泵导入采样管线和样品环。(2)载气将样品环中的气体带入色谱系统，通过预分离柱和分析柱使样品气中的氨与其它组分分离。
