NEW HYDROGEN PURIFIER

table-top unit separates ten cubic feet of dry, ultra-pure hydrogen per hour Wherever pure hydrogen is needed and impure hydrogen is available, t h e Model C Serfass Purifier can provide a constant, economical, trouble-free source. Presently available analytical techniques a r e not sufficiently sensitive to determine any impurities in the hydrogen separated by this new i n s t r u m e n t . I m p u r e hydrogen under p r e s s u r e is passed over a resistance-heated bundle of palladium alloy tubes. Hydrogen and deuterium pass t h r o u g h t h e tubes, b u t all other gases a r e barred. Unlike p u r e palladium, the special alloy will never become b r i t tle, needs no p u r g i n g or system evacuation. Typical feed gases for t h e purifier include impure hydrogen, forming gas, cracked ammonia, and cylinder hydrogen. The model C will s e p a r a t e fifteen cubic feet of hydrogen per hour at differential p r e s s u r e s to 100 psi with a maximum outlet p r e s s u r e of 150 psi. L a r g e r capacity u n i t s a r e available on special order. FOR C O M P L E T E F A C T S on t h e Serfass Model C Hydrogen Purifier w r i t e for Bulletin 1159.
