氣體分析法是煤礦自然發(fā)火早期預(yù)測預(yù)報的主要方法之一，以co、h2、c2h2及鏈烷比、烯烷比等為主的標(biāo)志氣體指標(biāo)體系在我國已經(jīng)得到廣泛的應(yīng)用，因此礦山災(zāi)害氣體分析是保障煤礦安全的重要工作之一。

由于煤礦災(zāi)害氣體由多組分氣體組成，同時常量和微量共存，目前的常規(guī)分析分析往往要采用兩臺色譜儀，即使采用一臺色譜儀的也是采用一次進樣切換，不僅分析時間較長，而且造成組分之間互相干從而擾影響組分測定的準(zhǔn)確性，有可能造成對災(zāi)害原因產(chǎn)生誤判進而對救災(zāi)防爆產(chǎn)生不利的影響。

因此，在一臺儀器上，在盡可能短的時間內(nèi)進行煤礦災(zāi)害氣體多組分全分析，煤礦安全生產(chǎn)、防止自燃爆炸等災(zāi)害的發(fā)生，是煤礦安全生產(chǎn)管理體系中急需解決的問題。

對于微量一氧化碳，二氧化碳的測定，傳統(tǒng)方法是安裝甲烷轉(zhuǎn)化爐。體積大，安裝復(fù)雜，效率低下，實用性不好，況且還要改造儀器，費時費力，成本高昂。

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)化爐成功應(yīng)用在PE690氣相色譜儀上，微量一氧化碳，二氧化碳分離好，柱效高，集成化高，渾然一體，安裝簡單，調(diào)試方便。浩瀚色譜，提供完整的分析方案。

Methane reformer for PerkinElmer gas chromatograph
Methane reformer for PerkinElmer gas chromatograph Details:

The gas analysis method is one of the main methods for early prediction and prediction of spontaneous combustion in coal mines. The indicator gas index system based on co, h2, c2h2, alkane ratio, and alkane ratio has been widely used in my country. Therefore, mine disaster gas Analysis is one of the important tasks to ensure coal mine safety.

Since coal mine disaster gas is composed of multi-component gases, and both macro and trace amounts coexist, the current routine analysis and analysis often use two chromatographs. Even if one chromatograph is used, one injection switch is used, which not only takes a long time, but also In addition, the components interfere with each other and affect the accuracy of the component determination, which may cause misjudgment of the cause of the disaster and adversely affect the disaster relief and explosion protection.

Therefore, it is an urgent problem in the coal mine safety production management system to conduct a multi-component full analysis of coal mine disaster gas in the shortest possible time on one instrument to ensure coal mine safety production and prevent spontaneous combustion and explosion.

For the determination of trace carbon monoxide and carbon dioxide, the traditional method is to install a methane reformer. Large size, complicated installation, low efficiency, poor practicability, and the need to modify the instrument is time-consuming, laborious, and costly.

Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. keeps pace with the times and has successfully applied the micro methane converter to the PE690 gas chromatograph. It has good separation of trace carbon monoxide and carbon dioxide, high column efficiency, high integration, integration, simple installation, Easy to debug. Haohan Chromatography provides a complete analysis program.
