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.
