An X-ray diffraction apparatus provides analysis in either transmission or reflective mode and easy conversion between the two modes. An X-ray source and X-ray detector are each connected to a different circle of a goniometer. The two circles may be rotated independently to position the source and detector on the same side of a sample library for reflection mode operation, or on opposite sides of the sample library for transmission mode operation. The sample library has a horizontal orientation that allows open sample containers of the library to maintain the sample without spillage, and it connects to an XYZ stage that can move in three dimensions. The system may use a beamstop, and the goniometer and XYZ stage be motorized and controlled for automated sample analysis.

X-ray diffraction screening system convertible between reflection and transmission modes

A transmission mode x-ray diffraction screening system has a sample support that holds a sample tray with multiple samples to be tested. The sample support is connected to a translation stage that is movable in three dimensions, and that it offset from the location of the sample support. An x-ray source is located to one side of the sample support, and a detector is located to the other side, thereby allowing the detection of x-rays that are diffracted by the sample in a transmission mode. A retractable beamstop may be located between the sample and the detector to block at least part of the non-diffracted x-rays from the source. A video camera may also be provided for imaging the sample location, which may be illuminated by a laser. The entire system may be automated such that each sample in the sample tray may be sequentially analyzed.
