使用熱導池為檢測器，氣相色譜法分析氣體中一氧化碳和二氧化碳時只能檢測到較高的含量，對于氣體中μg級一氧化碳和二氧化碳的分析,受熱導池檢測器檢測限的影響,不能滿足分析要求，而一氧化碳和二氧化碳在氫焰檢測器上又無響應，因此可采用甲烷轉化法，將一氧化碳和二氧化碳加氫轉化成甲烷，再由氫焰檢測器來檢測 。

K.Porten和D.V.Volman在1962年介紹了將CO，CO2，H2等催化還原生成甲烷后用氫火焰離子化檢測器進行檢測。Johns和Thomson進一步證實了這一方法, 并測定了每種氣體的操作參數,目前氣體中微量碳的分析方法有多種途徑，但其中為簡單快捷的是氣相色譜中甲烷轉化爐法。樣品通過色譜柱實現組分的分離，在甲烷轉化爐中由Ni(鎳)觸媒將分離的一氧化碳和二氧化碳加氫轉化為甲烷，而后再通過氫焰檢測器檢出。
應用：

Methane reformer unit 2021
Methane reformer device 2021 detailed information:

Using the thermal conductivity cell as the detector, gas chromatography can only detect higher levels of carbon monoxide and carbon dioxide in the gas. For the analysis of μg-level carbon monoxide and carbon dioxide in the gas, the detection limit of the thermal conductivity cell detector cannot be satisfied. Analysis requirements, and carbon monoxide and carbon dioxide have no response on the hydrogen flame detector, so the methane conversion method can be used to hydrogenate carbon monoxide and carbon dioxide into methane, which is then detected by the hydrogen flame detector.

In 1962, K. Porten and D.V. Volman introduced the catalytic reduction of CO, CO2, H2, etc. to generate methane, which was then detected by a hydrogen flame ionization detector. Johns and Thomson further confirmed this method and determined the best operating parameters for each gas. There are many ways to analyze trace carbon in gases, but the simplest and fastest method is the methane reformer method in gas chromatography. The sample is separated by a chromatographic column. The separated carbon monoxide and carbon dioxide are hydrogenated into methane by Ni (nickel) catalyst in the methane reformer, and then detected by a hydrogen flame detector.
application:
1. The methane reformer method in gas chromatography is mainly used for gas chromatography to analyze trace carbon monoxide and carbon dioxide in propylene and ethylene;
2. Trace carbon monoxide and carbon dioxide in hydrogen;
3. Trace carbon monoxide and carbon dioxide in high-purity permanent gas;
4. Analysis of dissolved gas in transformer oil;
5. Analysis of carbon monoxide and carbon dioxide in the production of synthetic ammonia from chemical fertilizers.
