Hi Mikhail,
Could Hydrogen taken orally provide extra
oxygen into the bloodstream?

Yes, good point Neal. Sometimes
ago, we bought a hydrogen gas generating instruments using electrolysis of
water to provide H2 for our GCs. It works well, but needs to be
maintained.

Subject: [DCHAS-L] Handling O2 and
H2
Labs
tend to have cylinders of H2 and O2 which pose risks that
can be easily mitigated by reducing the quantity of gas. For the
researcher, all that is needed is a reliable gas source of sufficient volume
and pressure to do the job. For the risk managers, the issue adds
reducing the risk along with meeting the research needs. One proven way
to do this is to generate O2 and/or H2 locally via the
electrolysis of water.
I
am looking at a resource that will deliver either or both gases at a pressure
of about 1500 psi (100 bar) and a volume of 1 liter per minute (that is a
lot!).
It
is locally generated and a simple power interruption removes the hazards
associated with each gas.
So,
my questions to the list are simple -
Is
this of interest to you?
Is
$25k USD reasonable to replace all of the H2 (or O2)
cylinders in the chemistry department?
The
big downside of this is having a single source within a department. Major
research departments will likely want several. A look at the demurrage
costs of cylinders will easily make the $25k ( and low annual maintenance) seem
reasonable.
I
look forward to your comments and questions…
Incidentally,
I do not have any financial involvement with the above; it was presented to me
as a solution to a problem I have worked on for years – too damn many
cylinders in labs….
