1.1 This test method describes a procedure for the determination of cations in hydrogen and other fuel cell feed gases. It has been successfully applied to other types of gaseous samples including air, engine exhaust, and landfill samples. An ion chromatograph\/conductivity detector (IC\/CD) system is used to determine cations. Sensitivity from low part per billion (ppb, ?<\/span> g\/l, ?<\/span> g\/kg) up to part per million (ppm, mg\/l, mg\/kg) concentration are achievable dependant on the amount of hydrogen or other fuel cell gas sampled. This test method can be applied to other gaseous samples requiring analysis of trace constituents provided an assessment of potential interferences has been accomplished.<\/p>\n

1.2 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.<\/p>\n

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.<\/span><\/p>\n
