Combined electrolytic hydrogen gas separator and generator for gas chromatographic systems
Abstract
Abstract A COMBINED HYDROGEN GAS SEPARATOR AND GENERATOR DEVICE COMPRISING A PAIR OF THIS PALLADIUM FILM MEMBRANCE ELECTRODES SEPARATED BY AN AQUEOUS HYDROXIDE ELECTRLYTE. ON APPLICATION OF AN ELECTROLYTIC CURRENT TO THE FILMS HEATED TO A TEMPERATURE OF AT LEAST 150*C., HYDROGEN IS SELECTIVELY TRANSFERRED THROUGH THE FIRST FILM. ACROSS THE BODY OF ELECTRLYTE AS PROTONIC HYDROGEN AND IS REGENER- ATED AS DIATOMIC HYDROGEN ON THE OUTSIDE SURFACE OF THE SECOND FILM. THE IMPURITIES IN THE HYDROGE INLET STREAM COLLECT AT THE OUTSIDE SURFACE OF THE FIRST FIL,. THE CONCENTRATED IMPURITIES CAN BE SENT TO A DETECTOR FOR ANALYSIS. THE REGENERATED HYDROGEN CAN BE RECYCLED TO OPERATE A SEPARATOR UNIT SUCH AS A GAS CHROMATOGRAPHIC COLUMN.
