In the process of ethylene oxidation to ethylene oxide, a very small amount of dichloroethane should be added as a catalyst inhibitor to improve the selectivity of the catalyst. However, too much dichloroethane can cause poisoning and deactivation of the catalyst. Therefore, it is very important to accurately measure the content of ethylene dichloride below 0.4ppm in the feed gas for the oxidation of ethylene to ethylene oxide.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. keeps pace with the times and develops HH-EDC special packed column for the determination of trace dichloroethane in the raw gas of ethylene oxide to ethylene oxide, with high column efficiency, good separation, and no interference. The peak shape is symmetrical and the results are satisfactory. This column is a unique product of the vast chromatography.
