Agilent安捷伦7890A便携式小型甲烷化转化炉气相色谱仪HH-790CH4-GC

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。
因工作需要,浩瀚色谱（山东）应用技术开发有限公司，与时俱进，采用新技术，研发新方案，研制生产便携式甲烷转化炉，成功的安装在安捷伦7890A气相色谱仪上，运行良好，效果满意。

此款甲烷转化炉为外置式，安装简单，方便，快捷。用户可独立完成操作，效率高。此款甲烷转化炉是微型气相色谱仪的缩影：具有气路（稳压，稳流系统）结构，阀进样系统，反吹系统，切割流路，甲烷化催化模块，加热系统。
   
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 requirements of the analysis. 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 chromatograph that has been finalized.
Due to work needs, Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. keeps pace with the times, adopts new technologies, researches and develops new schemes, develops and produces portable methane converters, and successfully installs them on Agilent 7890A gas chromatographs. The operation is good and the results are satisfy.

This methane reformer is an external type, which is simple, convenient and fast to install. The user can complete the operation independently with high efficiency. This methane reformer is the epitome of a miniature gas chromatograph: it has a gas circuit (stabilizing, steady flow system) structure, valve sampling system, backflushing system, cutting flow path, methanation catalytic module, and heating system.
