氨水又稱阿摩尼亞水，主要成分為NH3?H2O，是氨氣的水溶液，無色透明且具有刺激性氣味。氨氣熔點-77℃，沸點36℃，密度0.91g/cm^3。氨氣易溶于水、乙醇。易揮發(fā)，具有部分堿的通性，氨水由氨氣通入水中制得。氨氣有毒，對眼、鼻、皮膚有刺激性和腐蝕性，能使人窒息，空氣中高容許濃度30mg/m^3，主要用作化肥。

工業(yè)氨水是含氨25%～28%的水溶液，氨水中一小部分氨分子與水反應(yīng)形成銨離子和氫氧根離子，即一水合銨，是僅存在于氨水中的弱堿。氨水凝固點與氨水濃度有關(guān)，常用的(wt)20%濃度凝固點約為35℃。與酸中和反應(yīng)產(chǎn)生熱。有燃燒爆炸危險。比熱容為4.3×10^3J/kg?℃﹙10%的氨水）。

Ammonia water, also known as Amonia water, is mainly composed of NH3?H2O. It is an aqueous solution of ammonia gas, which is colorless, transparent and has a pungent odor. The melting point of ammonia gas is -77°C, the boiling point is 36°C, and the density is 0.91g/cm^3. Ammonia is easily soluble in water and ethanol. It is volatile and has the property of partial alkali. Ammonia water is prepared by passing ammonia gas into water. Ammonia is toxic, irritating and corrosive to eyes, nose, and skin, and can suffocate people. The maximum allowable concentration in the air is 30mg/m^3. It is mainly used as fertilizer.

Industrial ammonia is an aqueous solution containing 25% to 28% of ammonia. only a small part of ammonia molecules react with water to form ammonium ions and hydroxide ions, namely ammonium monohydrate, which is a weak base that only exists in ammonia water. The freezing point of ammonia water is related to the concentration of ammonia water, and the commonly used (wt) 20% concentration freezing point is about 35 °C. The neutralization reaction with acid generates heat. There is a fire and explosion hazard. The specific heat capacity is 4.3×10^3J/kg?℃﹙10% ammonia water).

Due to the strong polarity of ammonia water, the traditional chromatographic stationary phase for the determination of ammonia water has low column efficiency, tailing peak shape, and large quantitative error. Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. keeps pace with the times and has developed a unique packed column for ammonia water. This column has high column efficiency, good separation, basically no tailing of ammonia and water, accurate quantification, and satisfactory results.
