Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 The gas chromatography/mass spectrometry
3、(GC/MS)procedure described in this method is used to determineconcentrations of total organic halides and total non-methanehydrocarbons (TNMHC) by measurement of individual targethalocarbons (Table 1) and hydrocarbons (includingformaldehyde, Table 1 and Table 2), respectively. Measure-ment of these
4、substances is required for application of SAEJ2719 to hydrogen fuel quality where this fuel is intended foruse in fuel cell vehicles. SAE 2719 states hydrogen fuel isexpected to contain less than 0.05 mole/mole total haloge-nates (including organic halides), 2 mole/mole total non-methane hydrocarbon
5、s (C1 Basis, 3.2.16) and 0.01 mole/moleformaldehyde.1.2 Based upon the GC/MS/full scan analysis of a 400 mLhydrogen sample, the reporting limit (RL) is 0.001 mole/molefor each target compound listed in Table 1 and Table 2, with theexception of 0.002 mole/mole for ethane and 0.002 mole/mole for ethen
6、e.1.3 Mention of trade names in this standard does notconstitute endorsement or recommendation for use. Othermanufacturers equipment or equipment models can be used.1.4 The values stated in SI units are to be regarded asstandard.1.5 This standard does not purport to address all of thesafety concerns
