Dear Andreas, This may not be an option for your sample but grinding the sample to less than 5 micron may help prevent fall out. In this size region, you may not need to spin the sample to reduce texture effects.
Dipo Omotoso -----Original Message----- From: Andreas Leineweber [mailto:[EMAIL PROTECTED] Sent: Thursday, September 09, 2004 7:57 AM To: [EMAIL PROTECTED] Dear all, when powder samples are measured in reflection on back-loaded samples on a theta-2theta diffractometer, there is always the danger that upon sample spinning the powder can fall out of its cavity. As a solution I tried a thin mylar foil, which, however, gives nasty background. Another procedure may be a little bit of glue (e.g. dissolved in a solvent to dillute it). Has somebody some practical good experiences with certain types of glues (influence on background, how much glue, which solvent) or does somebody know some further tricks. Thank you for your help Andreas PS. I am working with the Philips/Panalytical sample preparation equipment. -- Dr. Andreas Leineweber Max-Planck-Institut fuer Metallforschung Heisenbergstrasse 3 70569 Stuttgart Germany Telephone: +49 (0)711 689 3365 Telefax: +49 (0)711 689 3312 [EMAIL PROTECTED] http://www.mf.mpg.de/de/abteilungen/mittemeijer/english/index_english.htm
