Does anyone know where I can purchase the so-called "Hoko beads" platinum
catalyst for doing hydrogen-water equilibration? Is there a substitute
available that works?  I faxed the company (Shoko Co.) listed by Coplen in
the methods papers, but, was told the contact person was on holidays.
Repeated further attempts to contact over the past 6 months gave no reply.

Any help or suggestions would be appreciated.
