Ammonia (NH3.H2O) analysis of special packed column
氨水(NH3.H2O)分析专用填充柱
Industrial ammonia is ammonia 25% to 28% of the aqueous solution, ammonia, only a small part of ammonia molecules react with water to form ammonium ions and hydroxide ions, namely ammonium monohydrate, is only present in the ammonia in the weak base. Ammonia freezing point and concentration of ammonia, the commonly used (wt) 20% concentration of freezing point of about -35 ℃. Neutralization reaction with acid produces heat. Risk of combustion explosion. The specific heat capacity was 4.3 × 10³J / kg · ℃ (10% ammonia).
Because ammonia is corrosive, equipment and column life is short, and the chromatographic peak-shaped tail, quantitative error, no use value, can not promote the use of.
Tengzhou Xiangying Analytical Technology Co., Ltd. is advancing with the times and guided by scientific development. Under the leadership of General Manager Wang Xiaoying, we rely on Xiangying Chromatography Engineering Research Institute and Analysis and Testing Center, and make unremitting efforts. A special column for the analysis of industrial ammonia filled column, in a leading domestic level. This pillar-shaped symmetry, high efficiency, long life, is also second to none in the country.
工业氨水是含氨25%~28%的水溶液,氨水中仅有一小部分氨分子与水反应形成铵离子和氢氧根离子,即一水合铵,是仅存在于氨水中的弱碱。氨水凝固点与氨水浓度有关,常用的(wt)20%浓度凝固点约为-35℃。与酸中和反应产生热。有燃烧爆炸危险。比热容为4.3×10³J/kg·℃﹙10%的氨水)。
因氨水有腐蚀性,仪器和色谱柱使用寿命短,且色谱峰形拖尾,定量误差大,无使用价值,无法推广使用。
滕州市翔鹰分析技术有限公司与时俱进,以科学发展为指导,在王晓莹总经理的带领下,依托翔鹰色谱工程研究所和分析与测试中心2个科研单位,经过不懈努力,成功开发出工业氨水分析专用填充柱,在国内处于领先水平。此柱峰形对称,柱效高,使用寿命长,在国内也是首屈一指。
