在环氧乙烷后续的加工过程中（例如水解制乙二醇），如果CO₂含量过高，它可能会溶解在液体产品中形成碳酸，从而：
腐蚀后续工艺的设备管道。
引入不必要的酸性环境，影响某些精细化学反应的进程和产品质量。
导致产品纯度不达标。
环氧乙烷中二氧化碳的测定国标采用TCD检测器进行检测,灵敏度不够高,对环氧乙烷中二氧化碳的方法进行改进。
采用高灵敏度的微池TCD，市场还未完quan普及；传统的TCD灵敏度低下，无法测定国标中要求10ppm的二氧化碳的检测要求
浩瀚色谱（山东）应用技术开发有限公司，研制生产《甲烷转化炉色谱仪测环氧乙烷中CO2》：克服了环氧乙烷对二氧化碳的干扰，延长转化炉的使用寿命，效率高，结果满意。

The national standard for the determination of carbon dioxide in ethylene oxide uses TCD detector for detection, but the sensitivity is not high enough. Therefore, the method for detecting carbon dioxide in ethylene oxide is improved.
The use of highly sensitive micro cell TCD has not yet been fully popularized in the market; Traditional TCD has low sensitivity and cannot measure the detection requirement of 10ppm carbon dioxide in the national standard
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed and produced the "Measurement of CO2 in Ethylene Oxide by Methane Converter Chromatography": it overcomes the interference of ethylene oxide on carbon dioxide, prolongs the service life of the converter, has high efficiency, and satisfactory results.
Name: Methane Converter
Filler: Nickel Catalyst
Specification: HH-790CH4-GC
Application: GB/T 13098-2006, applicable to the determination of carbon dioxide in industrial ethylene oxide
