Is it a peak? Getting More Out of Your XRD Data with Monochromatic Bragg-Brentano Geometry
The detection of weak peaks and minor phase fractions is one of the age-old challenges in XRD. Modern XRD instrumentation has overcome this to a certain degree, but it still remains a challenge, especially in cases where weak diffraction peaks only appear in the low-angle regime or where the sample does not scatter X-rays very strongly (e.g. organics, pharmaceuticals, etc.). One way to improve the data quality is via the use of a primary monochromator that maintains the classic Bragg-Brentano parafocusing geometry for reflection measurements. These monochromators, as implemented in XRDynamic 500, can lead to a reduction in the measurement background, suppression of sample fluorescence, and even give a boost in measurement intensity for faster measurements. All of these factors make it much simpler to see weaker diffraction peaks and to identify and quantify minor phase fractions present in your sample.
