Rigaku R-Axis Spider
The Rigaku R‐Axis Spider is equipped with an image plate area detector which enables the use of microgram sample sizes due to the higher sensitivity of detection when compared to a CCD detector. In addition, the X‐ray beam is collimated, allowing the beam to be adjusted to match a specific sample. Another feature of the R‐Axis spider is the use of a ¼ χ goniometer which can be oscillated in ω, χ, and φ to produce powder patterns with minimized preferred orientation and provides a more accurate identification of a crystalline phase. The R‐Axis Spider is equipped with an Oxford Instruments Cryostream Plus capable of temperatures in the range of 80 – 500 K and is ideal for solid‐state phase transitions and decomposition studies.

- Powder patterns can be obtained on μg sized samples
- Variable temperature capabilities (80 – 500 K)Oscillation of samples in ω, χ, and φ creates diffraction patterns with minimized preferred orientation
- Variable beam spot size (0.3, 0.5, and 0.8 mm)
Bruker D8 Advance Powder X-ray Diffractometer:
The Bruker D8 Advance is a conventional powder X-ray diffractometer that uses a 1.6 kW sealed tube X-ray source (Cu) and a vertical circle theta:theta goniometer with a measurement circle diameter of 500 mm for optimal angular resolution. In this design, the sample is held horizontally allowing the use of a number of different sample holders. This system features a 60 mm sealed Göbel mirror that creates a highly parallel incident beam and suppresses Kβ radiation. Parallel beam optics minimize peak position and shape errors due to sample displacement, flat specimen defocusing, sample transparency, and rough and/or irregular surface geometries. The detector is a LynxEye linear position sensitive detector that allows for ultra fast X-ray diffraction measurements. Compared to a single point detector, a 2theta range of 3.3° at 500 mm is simultaneously covered which is roughly equivalent to 200 point detectors simultaneously collecting data. 2theta range is from 3° to 145° maximum. Minimum step size achievable is <0.01° 2theta.
