Analysis of Inorganic Major and Minor Compounds in Unashed Coal Samples

Coal is classified and valued according to its sulfur, phosphorous, volatile and ash content. The composition of ash can effect coal processing, handling and final usage. This application note demonstrates the use of the Epsilon 4 energy dispersive X-ray fluorescence spectrometer for the analysis of inorganic compounds (Na₂O, MgO, Al₂O₃, SiO₂, P₂O₅, S, K₂O, CaO, TiO₂, MnO, Fe₂O₃ SrO and BaO) in unashed coal samples.
