氨水的主要成分是NH3·H2O，是氨的水溶液，無色透明且有刺激性氣味。氨水易揮發(fā)，具有腐蝕性，廣泛應用在實驗室、工業(yè)生產(chǎn)、農業(yè)生產(chǎn)中。在氨水不同應用的使用過程中，對氨水濃度的要求也不一樣，國標上氨水濃度的檢定方法是采用酸堿滴定法，但這種方法比較復雜繁瑣。


浩瀚色譜（山東）應用技術開發(fā)有限公司建立了氣相色譜法測定氨氣中氨純度的分析方法，用HH-NH3-C2H2氨專用填充色譜對樣品進行分離，TCD檢測器檢測，用面積歸一化法作定量計算，測定結果的大相對標準偏差為0．17％。該方法分析速度快、操作簡單，滿足生產(chǎn)要求。

Model: HH-NH3-C2H2

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.
