天美氣相色譜儀用甲烷轉(zhuǎn)化爐 詳細(xì)信息：

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。

為此須增設(shè)一甲烷化爐,由于傳統(tǒng)的甲烷轉(zhuǎn)化爐體積大，既要連接氣路系統(tǒng)，還要接電路系統(tǒng)，操作復(fù)雜，費(fèi)時費(fèi)力，這對于已定型的色譜儀來說讓儀器使用者安裝是有困難的。

為了解決這一難題，滕州市浩瀚色譜儀器技術(shù)服務(wù)有限公司，，研發(fā)微型甲烷轉(zhuǎn)化爐CH4，成功應(yīng)用到天美各種型號的氣相色譜儀GC-0，GC-7980，GC-7980[LUS等。微量一氧化碳，二氧化碳分離良好，結(jié)果滿意。

Methane reformer for Tianmei gas chromatograph
Methane reformer for Tianmei 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, it is necessary to add a methanation furnace. Due to the large volume of the traditional methane reforming furnace, it is necessary to connect the gas circuit system and the circuit system. The operation is complicated, time-consuming and labor-intensive. This makes the instrument users for the finalized chromatograph Installation is difficult.

In order to solve this problem, Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. keeps pace with the times and develops a miniature methane converter CH4, which has been successfully applied to various types of Tianmei gas chromatographs GC-0, GC-7980, and GC-7980 [LUS et al. Small amount of carbon monoxide, good separation of carbon dioxide, satisfactory results.
