A Beryllium Dome Specimen Holder for Xrd Analysis of Air Sensitive Materials
A specially designed specimen holder employing a beryllium dome has been fabricated for collection of XRD data from highly reactive materials. The specimen holder has a robust o-ring type seal (>10 torr) and no observed intensity artifacts in the 1° to 150° 2θ range. The design also minimizes specimen displacement errors and allows for analysis of both powders and bulk specimens (i.e., pellets)...
متن کاملVibrating Sample Holder for Xrd Analysis with Minimal Sample Preparation
A new approach to sample handling for powder X-ray diffraction analysis is presented that allows characterization of poorly prepared samples. The technique relies on vibrations generated in a sample holder to create movement of the powdered sample in the absence of macroscopic movement of the sample holder itself. The major benefits over conventional sample handling strategies are: 1) the abili...
متن کاملA scanning electron microscopy specimen holder for viewing different angles of a single specimen.
The specimen holder for scanning electron microscopy described herein allows a single specimen to be examined in any possible view and significantly improves object illumination. The specimen is glued to a fine pin and flexibly mounted on a double-sided adhesive conductive pad on a rotatable pivot. A milled pot placed beneath the specimen acts as an electron trap. This provides a homogeneous bl...
