Gas flow sample heating?

I am working on an idea for using heated N2 as means of heating up a 
small polymer sample for WAXD and/or SAXS. I am considering this approach 
because I would like to reorient the sample freely and I wish to minimize 
the blockage of diffracted and scattered and scattered rays. The approach 
would be analogous to what the biological people do for their single 
crystal structure work. I would like to be able to go as high as 200 deg 
C or so.

I'm virtually certain that this has been done before and I would 
appreciate any references that sa_scat subscribers could provide.

Thank You
