Scope

This document describes the principle, reagents and materials, instruments and
equipment, samples, test procedures, test data processing, precision and accuracy,
quality assurance and control, and test report for the determination of helium, argon,
nitrogen and hydrocarbon components in hydrogen for proton exchange membrane fuel
cell vehicles using gas chromatography-thermal conductivity detector/flame ionization
detector method.
This document is applicable to the determination of the content of helium, argon,
nitrogen and hydrocarbon components in hydrogen for proton exchange membrane fuel
cell vehicles. The determination of the content of helium, argon, nitrogen and
hydrocarbon components in hydrogen for other purposes within the content range
specified in this document shall be carried out as a reference.
The measurement range of various components in this document is. helium. 10.0
μmol/mol~600.0 μmol/mol; argon. 5.0 μmol/mol~300.0 μmol/mol; nitrogen. 5.0
μmol/mol~300.0 μmol /mol; methane (C1) in hydrocarbons. 0.10 μmol/mol~200.0
μmol/mol; C2~C6 components and toluene in hydrocarbons. 0.10 μmol/mol~2.0
μmol/mol.
NOTE. Hydrocarbons in this document refer to hydrocarbons that may be present in hydrogen,
including alkanes, alkenes, alkynes and aromatics.
