X-ray fluorescence spectrometry is a rapid, precise, and accurate method to meet the requirements of silicate rock analysis. It can also simplify and reduce sample preparation compared to other spectroscopic analysis methods, which use wet chemical techniques. This note describes an XRF method with a low dilution fusion technique applied to silicate rock samples, which can widely determine major elements to trace elements with high accuracy.

Limestone is widely used as the main ingredient in cement and mortar, and as an aggregate in concrete and asphalt for building roads. It is also used as a soil conditioner and is the raw material for making quick lime and slaked lime. During mining and processing operations, limestone composition must be monitored and controlled to ensure proper quality and characteristics are achieved for a variety of products. This application note demonstrates the measurement of carbonates and major oxides in high calcium limestone by EDXRF using empirical calibration.

Hard disk manufacturing requires high levels of precision at nanometer scale for the production of a repeatable product with high memory density. Because hard disks are dependent upon magnetic properties to read and write to each memory unit, the disk has a layered structure comprised of magnetic and nonmagnetic materials. Over the last two decades, extensive work has been done by hard disk manufacturers to reduce grain size, which enables smaller, but consistent magnetic domain sizes and distinct boundaries. This movement toward tighter anufacturing tolerances requires advanced techniques for characterization. Compositional depth profiling with GD-AES enables precise characterization of the size of these thin layers of material.
