　　Determination of trace amounts of carbon monoxide and carbon dioxide in industrial ethylene and propylene by gas chromatography

　　This standard specifies the gas chromatography method for the determination of trace amounts of carbon monoxide and carbon dioxide in industrial ethylene and propylene. This standard is applicable to the determination of carbon monoxide with a concentration greater than 1 mL/m3 and carbon dioxide with a concentration greater than 5 mL/m3 in ethylene and propylene.

　　Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses a hydrogen flame gas chromatography and chromatography workstation with a conversion furnace to detect trace amounts of carbon monoxide and carbon dioxide in industrial ethylene and propylene by selecting appropriate operating conditions and standard gas samples. The detection limit of the method reaches μ Level of L/m3. The recovery rate and precision of the method were tested, and the recovery rate was determined to be 97.1% -103.9%, with a relative standard deviation (n=6) of 2.67% -7.40%.
