在色譜分析中,利用熱導(dǎo)池鑒定器分析微量CO、CO_2,往往因靈敏度不夠而不能滿足分析的要求。氫火焰鑒定器雖然靈敏度較高,但必須將CO、CO_2等轉(zhuǎn)化為CH_4,才能出現(xiàn)色譜信號(hào)。為此須增設(shè)一甲烷化柱,這對(duì)于已定型的色譜儀來(lái)說是有困難的。

滕州市浩瀚色譜儀器技術(shù)服務(wù)有限公司，在 捷島GC-1690型氣相色譜儀上加裝轉(zhuǎn)化爐、定量管 ,用氫焰檢測(cè)器可分別測(cè)定大氣中的CO和CH3 OH含量 ,其CO低檢出濃度達(dá) 0 .2mL/m3 ( 2mL氣樣 )。本法回收率為 94%～ 10 6 % ,與奧氏氣體分析法比較統(tǒng)計(jì)檢驗(yàn)無(wú)顯著差異。具有簡(jiǎn)便、快速的優(yōu)點(diǎn) ,同時(shí)也充分利用了現(xiàn)有設(shè)備。

此款甲烷轉(zhuǎn)化爐，安裝簡(jiǎn)單，方便，化驗(yàn)室工作人員即可單獨(dú)完成，體積小，和儀器融合一體。

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.
