国标环氧乙烷中杂质二氧化碳是必检项目之一，标准采用的是热导检测器，灵敏度低，很难测定10ppm的二氧化碳，需要高灵敏度TCD，价格高，不易普及。
浩瀚色谱研制甲烷转化炉氢火焰气相色谱法测定环氧乙烷中二氧化碳的含量，采用带反吹的气路系统，二氧化碳可以测定0.5ppm以下，灵敏度高，结果准确。在安捷伦，岛津，赛默飞，瓦里安，布鲁克，PE上安装，得到用户的认可。
名称：便携式甲烷转化炉
型号：HH-790CH4-GC
适合于：安捷伦4890. 5890, 6890, 7890, 7820, 8860, 8890气相色谱仪上
浩瀚色谱研制生产：外置式甲烷转化器，具有小巧玲珑，方便携带，安装简单（用户可完成安装），集成化高（含气路系统，进样系统，温控系统，分离系统），可扩展二维/多维系统，反吹，切割系统。一机多用，实用价值高。
The impurity carbon dioxide in the national standard ethylene oxide is one of the mandatory inspection items. The standard uses a thermal conductivity detector, which has low sensitivity and is difficult to measure 10ppm of carbon dioxide. High sensitivity TCD is required, which is expensive and not easy to popularize.
Haohan Chromatography developed a hydrogen flame gas chromatography method for the determination of carbon dioxide content in ethylene oxide using a methane conversion furnace. Using a gas path system with backflow, carbon dioxide can be measured below 0.5ppm with high sensitivity and accurate results. Installed on Agilent, Shimadzu, Thermo Fisher, Varian, Brooke, and PE, and received user recognition.
Name: Portable methane conversion furnace
Model: HH-790CH4-GC
Suitable for: Agilent 4890, 5890, 6890, 7890, 7820, 8860, 8890 gas chromatographs
Haohan Chromatography Development and Production: External methane converter, small and exquisite, easy to carry, easy to install (user can complete installation), highly integrated (including gas path system, injection system, temperature control system, separation system), expandable two-dimensional/multi-dimensional system, backflow, cutting system. One machine is versatile and has high practical value.
