前，使用者有责任制定相应的安全和保护措施，明确其限定的适用范围，并保证符合国家有关法律法

规、强制性国家标准的规定。

1范围

本文件描述了采用气相色谱⁃热导检测器/火焰离子化检测器法测定质子交换膜燃料电池汽车用

氢气中氦气、氩气、氮气和烃类组分含量的原理、试剂与材料、仪器与设备、样品、试验步骤、试验数据处

理、精密度和正确度、质量保证和控制、试验报告。

本文件适用于质子交换膜燃料电池汽车用氢气中氦气、氩气、氮气和烃类组分含量的测定，其他用

途氢气中含量范围在本文件规定范围内氦气、氩气、氮气和烃类组分含量的测定参照执行。

本文件中各类组分的测定范围：氦气，10.0μmol/mol~600.0μmol/mol；氩气，5.0μmol/mol~

300.0μmol/mol5.0μmol/mol~300.0μmol/molC0.10μmol/mol~200.0μmol/mol

；氮气，；烃类中甲烷（1），；

3术语和定义

本文件没有需要界定的术语和定义。

4原理

采用配置热导检测器和火焰离子化检测器的气相色谱仪，试样经进样管路被分成两路，一路进入

与十通阀相连的定量环，通过调节阀的开启和关闭时间，非目标组分经预分离柱反吹放空，目标组分氦

气、氩气和氮气经分子筛柱被分离，并由热导检测器检测；另一路试样进入与六通阀相连的定量环、三

氧化二铝色谱柱及火焰离子化检测器，实现烃类组分的分离和检测。采用外标法定量。
