Hydrogen purity assessment
Hydrogen, composition, impurities, ISO 14687, EN 17124
Purpose
Some impurities and particulates, if present in hydrogen may damage, the fuel cell system in a hydrogen vehicle as it is highly sensitive to the presence of even very low levels of impurities. Therefore, standards ISO14687 and EN17124 set stringent limits for numerous gaseous.
We offer flexible analyses to respond to every client´s need. We can analyse most of the impurities mentioned in these two standards, incl. water, total hydrocarbons, methane, oxygen, helium, nitrogen, argon, carbon dioxide, carbon monoxide, sulphur compounds, formaldehyde, formic acid, ammonia and halogenated compounds.
Method
Our analyses are performed in our gas laboratory which is equipped with many different analytical instruments incl. GC/TCD, GC/FID, GC/MS, Proceas (IR).
Deliveries
The results are first delivered per mail as a preliminary report. After an agreement, the final report is sent per mail.
