Indeed. In particular it seeps through almost all metals. (See also: https://en.wikipedia.org/wiki/Hydrogen_embrittlement) The canonical filter method for hydrogen is to press it through a "filter" which is a of solid slab of Palladium. Helium is almost as bad, but is better in leak-checks because it is non-reactive. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [email protected] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
