浩瀚HH-NH3焦炉煤气中氨含量的定量测定专用填充柱

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+,建立了含有酸性气体的氨的定量测定方法。

此法操作复杂，费时费力，不环保，分析时间长，无法工业大规模生产检测的需求。

气相色谱法测定焦炉煤气中氨，由于传统的固定相拖尾严重，定量误差大，无法准确测定。浩瀚色谱（山东）应用技术开发有限公司，与时俱进，研发2020款HH-AM氨专用固定相，测定焦炉煤气中微量氨，柱效高，分离好，不拖尾，结果满意。浩瀚色谱，独树一帜的产品。

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, and a quantitative determination method of ammonia containing acid gas was established.

This method is complicated to operate, time-consuming and labor-intensive, not environmentally friendly, and takes a long time to analyze, which cannot meet the needs of industrial large-scale production testing.

The determination of ammonia in coke oven gas by gas chromatography cannot be accurately determined due to serious tailing of the traditional stationary phase and large quantitative error. Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. keeps pace with the times and develops the 2020 HH-AM ammonia special stationary phase to measure trace ammonia in coke oven gas, with high column efficiency, good separation, no tailing, and satisfactory results. A vast spectrum of unique products.
