浩瀚焦炉煤气中氨测定专用填充柱HH-MQ-NH3-II

以酸碱中和反应为基础,用过量硫酸溶液吸收含氨气体,以甲基橙为指示剂,用氢氧化钠滴定中和试样中的游离酸;利用氨基与甲醛的特性反应,加入甲醛后,再用氢氧化钠滴定反应生成的H+。此法测定焦炉煤气中氨，操作复杂，费时费力，不环保，效率低下，不能满足工业大规模生产检测的需求，使用受限。

浩瀚色谱（山东）应用技术开发有限公司，采用新技术，研发新方案，研制生产气相色谱法测定焦炉煤气中氨，柱效高，分离好，结果准确可靠。

Based on acid-base neutralization reaction, excess sulfuric acid solution was used to absorb ammonia-containing gas, methyl orange was used as indicator, and the free acid in the sample was titrated with sodium hydroxide; the characteristic reaction of amino group and formaldehyde was used to add formaldehyde Then, the H+ generated by the reaction was titrated with sodium hydroxide. This method for the determination of ammonia in coke oven gas is complicated in operation, time-consuming and labor-intensive, not environmentally friendly, and inefficient.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. adopts new technologies, develops new programs, and develops and produces gas chromatography for the determination of ammonia in coke oven gas, with high column efficiency, good separation, and accurate and reliable results.

Name: Packed Column
Stationary Phase: Dedicated

Model: HH-MQ-NH3-II
Application: Determination of ammonia in coke oven gas

This column is well separated, and methane, ethylene, ethane, propane and propylene do not interfere with the determination of ammonia
