Hi Ryan --

Thanks for your interest in SNF!  I think, however, we don't have the 
resources to support this kind of project.  We are a user facility -- 
researchers perform their own experiments.  And although we deal with 
process gases like ammonia, our researchers don't deal directly with 
these gases -- rather, they use equipment which make use of these 
gases.  We don't really have the means to be able to allow researchers 
to deal with gas handling.

I'd like to invite you to visit our website at 
-- and more specifically, our lab wiki, which describes the process, 
tools, and capabilities we have --

To the first degree, I'm not sure we can support the kind of work you 
describe, but perhaps you can see something there that might meet your
