T/CPCIF 0381-2024 Gas analysis for determination of carbon dioxide, carbon monoxide, methane, nitrogen, argon (oxygen), helium and total hydrocarbon content in hydrogen used for proton exchange membrane fuel cells. Gas chromatography method

Scope

Scope: This document describes the method and method overview for determining the trace amounts of carbon dioxide, carbon monoxide, methane, nitrogen, argon (oxygen), helium, and total hydrocarbons in hydrogen using a gas chromatograph equipped with a methane converter and dual detectors (thermal conductivity and flame ionization). It specifies the test conditions, reagents or materials, instrumentation, samples, test procedures, test data processing, precision, detection limits, quantification limits, quality control and assurance, and requirements for test reports. This document is applicable to the determination of carbon dioxide, carbon monoxide, methane, nitrogen, argon (oxygen), helium, and total hydrocarbons in hydrogen used in fuel cell vehicles powered by proton exchange membrane fuel cells.
