天然气中O2,N2,CH4的测定
天然气中O2,N2,CH4的测定 详细信息：

名称：填充柱

规格：2米*mm

型号：13x分子筛

应用：天然气中O2,N2,甲烷的测定

为测定天然气制取的浓乙炔中的微量杂质气体,采用氢作载气,自制热导池为鉴定器,国产大华电子电位计为记录仪的气液色谱及气固色谱法,以水杨醛和液体石蜡混合固定液的色谱柱分离测定其中的丙二烯、甲基乙炔、丁二烯、乙烯基乙炔、丁二炔等五个组分,一次分析时间为18分钟。另以活性炭柱和5A分子筛柱串联及活性炭柱和硅胶柱串联,两次进样,分离测定其中氧、氮、甲烷、一氧化碳、二氧化碳、乙烯等组分,一次分析时间20分钟,本法的低检出浓度为1.1636.0×10~(-6),杂质气体含量在0.50.005％范围内的分析重复性以相对平均偏差表示±10％,准确度以相对平均误差表示±5％。

Determination of O2, N2, CH4 in Natural Gas
Determination of O2, N2, CH4 in Natural Gas Details:

Name: Packed column

Specification: 2 meters*mm

Model: 13x molecular sieve

Application: Determination of O2, N2, Methane in Natural Gas

In order to determine the trace impurity gas in the concentrated acetylene produced by natural gas, hydrogen is used as the carrier gas, the self-made thermal conductivity pool is used as the identification device, and the domestic Dahua electronic potentiometer is used as the gas-liquid chromatography and gas-solid chromatography of the recorder. The chromatographic column of aldehyde and liquid paraffin mixed stationary liquid was used to separate and determine the five components of propadiene, methyl acetylene, butadiene, vinyl acetylene, butadiyne, and the analysis time was 18 minutes. In addition, activated carbon column and 5A molecular sieve column in series, activated carbon column and silica gel column in series, two injections, separation and determination of oxygen, nitrogen, methane, carbon monoxide, carbon dioxide, ethylene and other components, one analysis time is 20 minutes, the lowest of this method The detection concentration is 1.16 to 36.0×10~(-6), and the repeatability of the analysis with impurity gas content in the range of 0.5 to 0.005% is expressed by the relative average deviation of ±10%, and the accuracy is expressed by the relative average error of ±5%.


Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. uses MS13X molecular sieve packed column to determine the content of O2, N2, CH4 in natural gas, with high column efficiency, good separation, and satisfactory results.
