[Ifeffit] sample holders

[Matt Newville]

Dear Silvio,

It may not be what you've used before, but Spex CeritPrep
(http://www.spexcp.com) has a line of XRF sample preparation products,
including liquid cells.  They're not suitable for transmission XAFS,
but I use them regularly for fluorescence measurements on dilute
solutions.  They do tend to be rather large volumes, but are easy to
work with.

You could also ask the people at the beamline you're working what they
have, and if they can lend you anything.
