Method of sample preparation for XRF by fusion as a reference method

In the cement industry, X-ray fluorescence analysis (XRF) is one of the major techniques employed for raw material and final product quality control. Typically, “pressed pellet” sample preparation is used; however, the disadvantage to this is that this technique shows only relative data to known and accepted reference methods like fusion or wet chemistry and takes no account of the different mineralogical effects, such as grain size and matrix effects that may or may not occur.
