A rapidly filled capillary mount for both dry powder and polycrystalline slurry samples

A method of rapid capillary sample loading of either dry powder or polycrystalline slurry has been developed. By embedding a Millipore filter in a Kapton capillary tube, one can then draw either loose dry powder or polycrystalline slurry into the tube and pack the solid against the filter, creating a dense column of powder suitable for a Debye–Scherrer powder diffraction experiment.
