　　Using water as the absorption liquid to absorb ammonia in coal gas, the nitrogen content in the gas is analyzed using a total organic carbon/total nitrogen analyzer, and the ammonia content in the gas is calculated. This method is complex to operate and cannot meet the needs of rapid inspection.

　　Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a 2024 new HH-NH3-VI special packed column for the determination of ammonia in coal gas. The column efficiency is high, and the experimental results show that this method has the advantages of reliable data, good repeatability, simple operation, and strong anti-interference ability, with a relative standard deviation (RSD) of less than 0.5%..

　　Features: Overcoming the influence of large amounts of hydrogen and methane in coal gas, C2 hydrocarbons do not interfere with measurement, have high separation degree, and symmetrical peak shapes.

　　Name: Special filling column for ammonia in gas

　　Specification: 6m * 1/8

　　Model: HH-NH3-VI

　　Application: Determination of ammonia in coke oven gas by gas chromatography
