氨气中的氨纯度测定专用填充柱 详细信息：


名称：填充柱
固定相：专用
规格：2m*1/8
型号：HH-NH3
应用：工业氨水及气氨的色谱测定


气氨纯度的测定采用传统的吸收测定法,此方法操作繁琐,分析时间长,样品用量多,而且测定结果受人为因素影响较大,如吸收时气体流速的大小,液位读数的偏差及标准溶液滴定、终点判断等都会对测定结果造成较大的误差,而且吸收管有时密封不严出现倒吸现象,导致分析失败或结果不准确。

现改用气相色谱法测定氨气中氨纯度的分析方法,浩瀚色谱（山东）应用技术开发有限公司用HH-NH3氨专用填充色谱柱对样品进行分离,用热导检测器检测分离物,用外标法作定量计算,测定结果的大相对标准偏差为0.2%。该方法分析速度快、操作简单,重复性好,准确度高。可以满足生产要求,还可降低员工的人身伤害。

此柱柱效高，分离好，氨峰型对称，结果满意。此柱为浩瀚色谱，的产品。

Special packed column for determination of ammonia purity in ammonia gas
Packed column for the determination of ammonia purity in ammonia gas Details:

The determination of the purity of gas ammonia adopts the traditional absorption measurement method, which is cumbersome to operate, takes a long time to analyze, requires a lot of samples, and the measurement results are greatly affected by human factors, such as the size of the gas flow rate during absorption, the deviation and standard of the liquid level reading. Solution titration, end point judgment, etc. will cause large errors in the measurement results, and sometimes the absorption tube is not tightly sealed and sucks back, resulting in analysis failure or inaccurate results.

Now use gas chromatography to determine the analysis method of ammonia purity in ammonia gas. Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses HH-NH3 ammonia special packed chromatographic column to separate the sample, and the thermal conductivity detector is used to detect the separated substance. The external standard method was used for quantitative calculation, and the maximum relative standard deviation of the determination results was 0.2%. The method has the advantages of fast analysis speed, simple operation, good repeatability and high accuracy. It can meet the production requirements and reduce the personal injury of employees.

This column has high column efficiency, good separation, symmetrical ammonia peaks, and satisfactory results. This column is a unique product of the vast chromatography.
