X-ray diffraction system

 

 

We have a tabletop Phillips PW-1840 X-ray diffraction machine. This is a computer controlled instrument with both a chart recorder and computer data acquisition. It has a goniometer with an automatic divergence slit and a scan angle of ~0 to 120° 2θ. It is currently equipped with a cobalt tube using an iron filter. Samples can be introduced as smears on short glass slides (about 5 mm shorter than a typical petrographic microscope slide) or pressed into a shallow well in aluminum holders.
