杭州捷岛气相色谱仪专用甲烷转化炉 详细信息：

在色谱分析中,利用热导池鉴定器分析微量CO、CO_2,往往因灵敏度不够而不能满足分析的要求。氢火焰鉴定器虽然灵敏度较高,但必须将CO、CO_2等转化为CH_4,才能出现色谱信号。为此须增设一甲烷化柱,这对于已定型的色谱仪来说是有困难的。

滕州市浩瀚色谱仪器技术服务有限公司，在 捷岛GC-1690型气相色谱仪上加装转化炉、定量管 ,用氢焰检测器可分别测定大气中的CO和CH3 OH含量 ,其CO低检出浓度达 0 .2mL/m3 ( 2mL气样 )。本法回收率为 94%～ 10 6 % ,与奥氏气体分析法比较统计检验无显著差异。具有简便、快速的优点 ,同时也充分利用了现有设备。

此款甲烷转化炉，安装简单，方便，化验室工作人员即可单独完成，体积小，和仪器融合一体。

Hangzhou Jiedao gas chromatograph special methane reformer
Methane conversion furnace for Hangzhou Jiedao gas chromatograph Details:

In chromatographic analysis, the use of thermal conductivity cell identifiers to analyze trace amounts of CO and CO_2, often due to insufficient sensitivity, can not meet the analysis requirements. Although the hydrogen flame detector has high sensitivity, it must convert CO, CO_2, etc. into CH_4 before the chromatographic signal can appear. To this end, a methanation column must be added, which is difficult for the established chromatograph.

Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. installed a conversion furnace and a quantitative tube on the Jiedao GC-1690 gas chromatograph. The hydrogen flame detector can be used to determine the CO and CH3 OH content in the atmosphere. The lowest CO detection The output concentration reaches 0.2mL/m3 (2mL gas sample). The recovery rate of this method is 94%～106%, and there is no significant difference in statistical test compared with the austenite gas analysis method. It has the advantages of simplicity and speed, while also making full use of existing equipment.

This methane reformer is simple and convenient to install. The laboratory staff can complete it alone. It is small in size and perfectly integrated with the instrument.
