表面积 [m2/g]：450-600

MAOT [℃]：250

官能团内性：5

型号：Porapak R

规格：3m*3mm

应用：GB/T 27894.3-2011 天然气 在一定不确定度下用气相色谱法测定组分 第3部分：用两根填充柱测定氢、氦、氧、氮、二氧化碳和直C8的烃类

本部分给出了用两根填充柱定量测定天然气中He、H2、O2、N2、CO2和C1C8烃类的气相色谱法。该方法适用于实验室和在线分析检测，可分析组分摩尔分数在表1范围内的气体，但不能含有液态烃。该范围并不代表检测限，而是本方法所规定的度的限制范围。即使样品中可能有一个或多组分不存在，该方法仍可适用。 本部分仅与GB/T27894第1、2部分配合使用。

Application: GB/T 27894.3-2011 Natural gas Determination of components by gas chromatography under certain uncertainty Part 3: Determination of hydrogen, helium, oxygen, nitrogen, carbon dioxide and hydrocarbons up to C8 with two packed columns

This section presents a gas chromatography method for the quantitative determination of He, H2, O2, N2, CO2, and C1 to C8 hydrocarbons in natural gas using two packed columns. This method is suitable for laboratory and on-line analysis and detection. It can analyze gases whose component mole fraction is within the range of Table 1, but cannot contain liquid hydrocarbons. This range does not represent the detection limit, but the limit range of the degree specified by this method. Even if one or more components may not be present in the sample, this method is still applicable. This part is only used in conjunction with Part 1 and Part 2 of GB/T27894.
