Compound analysis of limestone prepared as pressed powder pellets

This data sheet investigates the capability of the Epsilon 4, a benchtop energy dispersive X-ray fluorescence spectrometer (EDXRF), as an analytical tool for a complete analysis of the quality and composition of limestone.

Limestone is the principal source of CaCO3, which is used as raw material in a wide range of applications. It is used as an additive in steel making, as main component for cement and, when purified, it even can be used as supplement for calciumrich animal feed or pharmaceutical fillers. Al2O3, SiO2, MgO and Fe2O3 are further considered as the main compounds of limestone, and are important in the use of limestone. The grade and application of the raw material is determined by the ratio between these main compounds, as well as the presence of other minor and trace compounds, like MnO, P2O5 and Pb. In this data sheet, the Epsilon 4 was used for a full and accurate analysis of limestone.
