Hi all,
This thread gives me a chance to ask a question I've had for a long
time. I've heard about these large chambers where you can mix your
sample with a binder and have it fall out as small powder spheres to
avoid preferred orientation in Bragg-Brentano geometry. But, my samples
are mostly between 10 and 50 milligrams in size. Does anyone know a way
to mount them without preferred orientation? Thank you!
- Kurt

It's one of the classic needle-shaped materials - it gives lovely SEM
images if you can avoid charging

HI Pamela/all,
This sounds intriguing.. why is wollastonite a problem in capillary
transmission? Is it needle-like?

I do that myself but it doesn't always help much if you've got something
like wollastonite! :-)

Forget all that long winded stuff. Just collect the data on capillary
transmission geometry and avoid all (well, most of) the fuss.
