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).
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.
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
