Photograph of the sample changer hardware. Depicted are the motorized XYZ translation arm (A), the syringe needle (B), the temperature-controlled sample rack (C), and the temperature-controlled capillary holder assembly (D). The X-ray capillary is housed within a protective aluminium sheath (E) with two pairs of X-ray and UV/vis ports, perpendicular to the capillary long axis. A piece of plastic tubing is connected to the bottom opening of the capillary for drain collection (not depicted).
