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.
