​​​X-Ray Diffraction

WELLSITE     LAB-BASED



FGS uses a portable desktop BTX-II™ powder X-ray diffraction (XRD) machine that is equal to a traditional lab-based XRD in quality and function.  The BTX-II™ is the same XRD technology NASA currently uses on the Curiosity Rover now exploring the geology of Mars (NASA PDF).

The resulting XRD data is confirmed with the International Center Diffraction Data (ICDD) PDF II database falling within an error of 0.5%.  Pre-defined mineral species are set specific to geology of the region based upon our research of a given area or basin.  You can feel confident knowing we do our homework even ​before your first sample is analyzed.


xrdgraph.jpgThe difference in analysis between the traditional lab-based X-ray diffractor and the BTX-II™ is the technique the machine uses to analyze an aliquot of rock sample.  BTX-II™​analyzes a 10 – 15 mg of powdered sieved sample convected within an integrated sample vibration chamber.  This vibration chamber provides all orientations of the crystal structure to the instrument optics, resulting in a XRD pattern nearly free of problematic preferred orientation effects.  Also, energy discrimination by the X-ray detector eliminates any fluorescence, scatter and background noise.
