氨水的主要成分是NH3·H2O，是氨的水溶液，无色透明且有刺激性气味。氨水易挥发，具有腐蚀性，广泛应用在实验室、工业生产、农业生产中。在氨水不同应用的使用过程中，对氨水浓度的要求也不一样，国标上氨水浓度的检定方法是采用酸碱滴定法，但这种方法比较复杂繁琐。


浩瀚色谱（山东）应用技术开发有限公司建立了气相色谱法测定氨气中氨纯度的分析方法，用HH-NH3-C2H2氨专用填充色谱对样品进行分离，TCD检测器检测，用面积归一化法作定量计算，测定结果的大相对标准偏差为0．17％。该方法分析速度快、操作简单，满足生产要求。

The main component of ammonia water is NH3·H2O, which is an aqueous solution of ammonia, which is colorless, transparent and has a pungent odor. Ammonia is volatile and corrosive, and is widely used in laboratories, industrial production, and agricultural production. In the process of using ammonia water in different applications, the requirements for ammonia water concentration are also different. The test method of ammonia water concentration on the national standard is the acid-base titration method, but this method is more complicated and tedious.


Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established an analytical method for the determination of ammonia purity in ammonia gas by gas chromatography. The samples are separated by HH-NH3-C2H2 ammonia special packing chromatography, detected by TCD detector, and normalized by area. The method was used for quantitative calculation, and the maximum relative standard deviation of the determination results was 0.17%. The method is fast in analysis speed, simple in operation, and meets production requirements.
