The hot air gas blower for Bruker D8 VSC was funded by MAPEX
The Bruker D8 Venture four-circle single-crystal diffractometer in GEO 2380 is currently fitted with a hot air gas blower from XDS-Oxford. This allows for the advanced study of phase transitions and diffuse scattering phenomena of single crystals as a function of temperature. Temperature control with a precision of ±1°C is possible between room temperature and ~1000°C.
The upgrade includes: A hot air gas blower and a pre-calibrated controller with a computer software interface. The functionality has currently been successfully tested ex-situ, and the next step is to adapt the stand to the diffractometer housing for convenient operation. The system will then be calibrated to minimize the offset between factory-calibrated and actual temperatures.
Key benefits: The temperature-dependent behaviour of crystal structures can be studied with exceptional temperature stability and accuracy in situ.
Usage: To use the system, the hot air blower is aligned to the center of the single crystal with a precision of less than 0.1 mm, using a well- centered micro-thermocouple in the position of the single crystal. The micro-thermocouple will then be replaced by a 50–200 µm single crystal, fixed to the sample holder with high-temperature ceramic glue.
Features: The system enables detailed analysis of changes to and transitions in crystal structures based on high-quality data collected at user-selected temperatures.
