Thanks for all your comments regarding kapton tape and measuring air and moisture sensitive compounds. Many of my samples are indeed air sensitive and not just moisture sensitive (iron nanoparticles). If my particles are dispersed in solvent will the kapton be resistant to that solvent (at least during the time that the solvent is evaporating from the tape in the glove box)? Darek mentioned kapton dots - could you tell me where I can purchase these?
Thanks again for everyone's help, I thought this mailing list was primarily for software related questions but I am finding it is useful to get help on any XAFS related questions.
Todd

Good point on the cardboard, Richard. I always pre-cut strips of Kapton tape, so that I wasn't bringing in cardboard at all.

Todd,
Are you working with oxygen sensitive or moisture sensitive samples
(or both)? If it's just moisture sensitive, then you can use regular
2-sided tape from your local office supply and polypropylene film to
seal samples in polycarbonate or aluminum holders (or even pellets if
you're lucky enough to be able to press pellets that hold their
shape). Chemplex Industries is where I have gotten the polypropylene
films I have used (and Kapton as well - www.findtape.com also has a
good selection of Kapton tape).
I used this method with many samples that involved heavily chlorided
titanium on silica and had few problems if they're used within 5-7
days after packing in a glove box (the samples with problems resulted
from improperly sealed samples). You can get jars (baby food jars
work very well to ship individual samples) to store the samples for
shipping and if you pack the jars in the glove box, you will have the
box atmosphere in the jars, for a little while anyway.
A note on oxygen sensitivity (and to an extent moisture
sensitivity): you probably already know this, but I'll say it
anyway...if cardboard is present in the role of Kapton tape, you may
have oxygen/water diffusion from the cardboard for a few days after
you take it into the box. Our rule of thumb was to pull vacuum on
anything involving cardboard for at least 48 hrs before taking it into
the box. All that to say, take your supplies into the box a few days
ahead of time to allow your box catalyst to take care of any residual
oxygen/water that make their way in.
HTH,
-Richard
