| The Rigaku Smartlab X-ray
Diffractometer was acquired in 2014. We use a copper target X-ray source. The XRD is
equipped with two detectors: a high-efficiency scintillation detector and the D/tex Ultra 250
high speed silicon strip 1D detector for faster analyses. We have a monochrometer for use with the
scintillation detector for eliminating iron fluorescence.
The system is fully automated, with software to help beginning users set up and run simple analyses safely. | |
| X-ray Detectors | |
| The Smartlab is equiped with two different X-ray Detectors. The scintillation counter is best for powder XRD
when the user intends to perform quantitative Rietveld analyses. A monocrometer can be installed in-line for use with
this detector. The monochrometer damps the background resulting from fluorescence of iron or base metals in the
sample. We also have the D/tex 1-D strip detector, which collects X-rays across a 5 degree range simultaneously. This speeds up analysis, particularly when counts are low due to small sample or collimating the beam. Excellent for very quick bulk analyses and microdiffraction. | |
| Stages and Sample Holders | |
| We have three sample stages for the Smartlab XRD. The general measurement stage holds one sample at a time, and permits
the use of back-packed sample holders and glass slides. It also holds the "center slit" for beam alignments. The second stage is a 10-disk automated sample changer. It holds circular sample dishes (front-pack only), including the zero-background silicon wafer sample holders for use with very small amounts of powder. The third sample stage is an automated programmable x-y-z stage for microdiffraction. This stage has an x-y range of almost 10 cm, z-range of several cm, and can support samples up to 1 kg. | |
