Getter pump for hydrogen and hydrocarbon gases

Patent ·
OSTI ID:5957937
A gettering device for hydrogen isotopes and gaseous hydrocarbons based on the interaction of a plasma and graphite used as cathodic material. The plasma is maintained at a current density within the range of about 1 to about 1000 mA/cm/sup 2/. The graphite may be heated to a temperature greater than 1000/sup 0/C. The new device offers high capacity, low noise, and gas species selectivity.
