Geological samples are formed by constant deposits of inorganic and organic materials over millions of years. As layer of deposit accumulate upon layer, the weight creates pressure and increased temperature creating rocks or other formations. Over time, these formations are eroded and carried away by rain, wind and snow and deposited in streams and lake beds.
Analysis of these materials is of importance as it gives not only indications of the mineral bodies present, but also environmental contaminates. Analysis of soil and sediment samples encompasses a vast variety of material and matrix types, with many elements to be analyzed having concentrations ranging from parts per million (ppm) levels to major weight percentages of the composition.
These attributes make accurate quantitative analysis ideal for wavelength dispersive X-ray fluorescence (WDXRF).
