Minerals/Oxides analysis, of samples such as ores, raw industrial materials, contaminations, and precious stones, is typically done by combination of determining the chemical composition using X-ray fluorescence spectrometry (XRF) and identifying and/or quantifying the mineral/oxide components using X-ray diffraction (XRD) method.  Secondary but nonetheless important methods such as scanning electron microscopy (SEM), energy-dispersive X-ray microanalysis (EDX), inductively-coupled plasma spectrometry (ICP) infrared spectroscopy (FTIR and NIR) and conventional light microscopy are also used whenever needed in our analysis.  Whether it is to determine or confirm the type of minerals/oxides or obtaining the precise composition (0-100wt%) or trace impurity analysis (with analytical sensitivity of part-per-million), EMSL can help you achieve your goals through our expertise and dedicated analytical service. 

Example:  XRD spectrum of an Augite (Pyroxene group) mineral sample.
