ENVIRONMENTALLY CONTROLLABLE SAMPLE HOLDER FOR X-RAY DIFFRACTOMETER (XRD)

摘要

An environmentally controllable sample holder for use with the sample changer (SC) of an X-ray diffractometer includes a sample holder (10) comprising a sample plate (24), a base (12) that can be removably attached to the sample changer, a heating element (14) positioned between the base and the sample plate, and a temperature sensor (TS) adapted to provide a feedback signal for use to control the temperature of the heating element. A housing (40) is provided for sealing enclosing the sample holder wherein the housing has an aperture (A) in the bottom thereof for sealing receiving the sample holder therein, and air inlet (42A) and air exit (42B) nozzles for introducing and exhausting gasses from the housing. A thermocouple (44) is provided in the housing, and the top portion (46) of the housing is formed from an X-ray transparent material.
