Batch methods for enriching trace impurities in hydrogen gas for their further analysis |
| abstract |
Provided herein are batch methods and devices for enriching trace quantities of impurities in gaseous mixtures, such as hydrogen fuel. The methods and devices rely on concentrating impurities using hydrogen transport membranes wherein the time period for concentrating the sample is calculated on the basis of optimized membrane characteristics, comprising its thickness and permeance, with optimization of temperature, and wherein the enrichment of trace impurities is proportional to the pressure ratio P hi /P lo and the volume ratio V 1 /V 2 , with following detection of the impurities using commonly-available detection methods. |
