Scope

This document describes the principle, reagents and materials, instruments and
equipment, system performance verification, test procedures, test data processing,
precision and accuracy, quality assurance and control, and test report for the
determination of sulfur compounds, formaldehyde and organic halides in hydrogen for
proton exchange membrane fuel cell vehicles using the pre-concentration-gas
chromatography-sulfur chemiluminescence detector/mass spectrometry detector
method.
This document applies to the determination of sulfur compounds, formaldehyde and
organic halides in hydrogen for proton exchange membrane fuel cell vehicles; it serves
as a reference for the determination of sulfur compounds, formaldehyde and organic
halides in hydrogen for other purposes within the range specified in this document.
The determination range of sulfur compounds in this document is 0.10 nmol/mol ~ 10.0
nmol/mol, and the detection limit of hydrogen sulfide is 0.01 nmol/mol. The
determination range of formaldehyde is 1.0 nmol/mol ~ 400.0 nmol/mol, and the
detection limit is 0.1 nmol/mol. The determination range of organic halides is 1.0
nmol/mol ~ 100.0 nmol/mol, and the detection limit of methyl chloride is 0.5 nmol/mol.
