X-Ray Fluorescence (XRF)
Supermini200 is the only manufactured high-power benchtop sequential wavelength dispersive X-ray fluorescence (WDXRF) spectrometer for elemental analysis. It analyzes an extensive range of elements in the periodic table starting from Fluorine (F) through to Uranium (U), and can be used on almost any material. The instrument is able to analyze complex matrix materials in the forms of liquid (water and oil), rock powders, polymer, film and coating, alloy, paints and metal phases with a wide range of concentration from trace to high levels.
To ensure the accuracy and precision of the results, sample preparation is the most important component of the XRF analysis. A fusion bead technique for solid samples is employed and optimized to achieve the highest possible level of homogeneity of samples. Loss on ignition is measured and reported along with elemental analysis to clients. We offer an alternative press pellet technique when the concentrations of trace elements such as REEs are of concern.
XRF results can be used in conjunction with XRD results and other analyses to provide a more comprehensive reservoir characterization, as it is able to determine quantitatively all elemental components including those that are amorphous and thus invisible in the XRD spectra (for example bitumen, silica, and some clays, etc.).
