质子交换膜燃料电池汽车用氢气

无机卤化物、甲酸的测定离子色谱法

警示：氢气是一种易燃易爆气体。本文件不涉及与其应用有关的所有安全问题。在使用本文件

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

本文件描述了采用离子色谱法测定质子交换膜燃料电池汽车用氢气中无机卤化物、甲酸含量的原

理、试剂和材料、仪器和设备、试验步骤、试验数据处理、精密度、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无机卤化物、甲酸含量的测定，其他用途氢气中

无机卤化物、甲酸含量的测定参照执行。氢气中无机卤化物、甲酸含量的测定范围为0.025μmol/mol~

0.5μmol/mol，氢气中氯化氢、氯气、溴化氢、甲酸组分的检出限分别为0.014μmol/mol、0.007μmol/

mol、0.002μmol/mol、0.001μmol/mol。

注：本文件中无机卤化物指氢气中可能存在的氯化氢、氯气和溴化氢。
