This present invention provides a sample changer for automatically changing from one sample to the next in support of high throughput X-ray powder diffraction data acquisition in a capillary geometry. The samples are mounted on the outer rim of a disk or turntable, with each sample having its capillary axis parallel to a radius emanating from the center of the disk on which the samples are mounted. Each sample is mounted on a separate motor shaft which permits the sample to be rotated about the longitudinal axis of the capillary during data acquisition. To change from one sample to the next, the disk or turntable is rotated about its axis thereby presenting in turn each new sample to a X-ray beam. When the data acquisition is completed for that sample, a new sample is rotated into the beam and its data collection is carried out.
