Gas chromatography techniques to evaluate the hydrogen permeation characteristics in rubber: ethylene propylene diene monomer

We established an ex-situ approach for evaluating hydrogen gasoline permeability by thermal desorption evaluation (TDA) gasoline chromatography (GC) and by self-developed diffusion evaluation software program. Absorbed hydrogen mass in rubber, associated to the GC-peak space, is recorded as a operate of elapsed time after decompressing the hydrogen below high-pressure. From the charging quantity (CH0) and …
