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 ________________________________ From: Whitfield, Pamela [mailto:[EMAIL PROTECTED] Sent: Thursday, May 08, 2008 9:16 AM To: Kurt Leinenweber Subject: RE: Preferred orientation? It's one of the classic needle-shaped materials - it gives lovely SEM images if you can avoid charging From: Kurt Leinenweber [mailto:[EMAIL PROTECTED] Sent: May 8, 2008 12:12 PM To: Whitfield, Pamela Subject: RE: Preferred orientation? HI Pamela/all, This sounds intriguing.. why is wollastonite a problem in capillary transmission? Is it needle-like? - Kurt ________________________________ From: Whitfield, Pamela [mailto:[EMAIL PROTECTED] Sent: Thursday, May 08, 2008 7:55 AM To: rietveld_l@ill.fr Subject: RE: Preferred orientation? I do that myself but it doesn't always help much if you've got something like wollastonite! :-) From: Martin [mailto:[EMAIL PROTECTED] Sent: May 8, 2008 10:51 AM To: rietveld_l@ill.fr Subject: RE: Preferred orientation? Forget all that long winded stuff. Just collect the data on capillary transmission geometry and avoid all (well, most of) the fuss.
