H2,O2,N2,CO,CH4,CO2六种气体的测定,一般三柱单阀单检测器通用型永久性气体分析系统。该系统由两根直热式填充毛细管分析柱(5A分子筛及碳分子筛)、一根填充型预柱、一个十通阀和一个热导检测器组成,可用于任何气体样品中H2,O2、N2、CO、CO2和CH4的定量分析.
此法操作复杂,费时费力,价格高,使用受限,无法普及。
浩瀚色谱(山东)应用技术开发有限公司,与时俱进,研发独树一帜的一种新的气相色谱法测定H2,O2,N2,CO,CH4,CO2六种气体,只需1根填充柱,柱效高,分离好,结果满意。
The determination of six gases, H2, O2, N2, CO, CH4, CO2, is generally a three-column, single-valve, and single-detector general-purpose permanent gas analysis system. The system consists of two direct thermal packed capillary analytical columns (5A molecular sieve and carbon molecular sieve), a packed pre-column, a ten-way valve and a thermal conductivity detector, which can be used for H2, O2, N2 in any gas sample Quantitative analysis of , CO, CO2 and CH4.
This method is complicated to operate, time-consuming and labor-intensive, expensive, limited in use, and cannot be popularized.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. keeps pace with the times and develops a unique new gas chromatography method for the determination of H2, O2, N2, CO, CH4, CO2 six gases, only one packed column, column High efficiency, good separation, and satisfactory results.
