Rigaku Application Note: Silicate Rock Analysis by Fusion Method
Date:1/22/2013

The Woodlands, TX (PRWEB) January 22, 2013

Rigaku Corporation today announced a new method for silicate rock analysis by wavelength dispersive X-ray fluorescence spectrometry (WDXRF). Rigaku Application Note XRF 5018 describes silicate rock analysis by the fusion method, highlighting the performance of the Rigaku ZSX Primus II WDXRF spectrometer, and includes details for sample preparation, method calibration and repeatability. The report demonstrates that an X-ray fluorescence spectrometry (XRF) method with a low dilution fusion technique applied to silicate rock samples can make a broad range of determinations, from major elements to trace elements, with high accuracy. The method covers most trace elements required for modern geochemical investigation, as well as rare earth elements.

Geochemical analysis of silicate rocks is an essential part of modern petrology. Concentrations of major and trace components in igneous rock samples provide important information about rock history, such as eruption or solidification, magma evolution and source materials, aiding in petrographic classification. XRF has been used for several decades for silicate rock analysis and is a standard technique for the determination of the chemical composition of major elements in silicate rocks.

Highly accurate rock analysis, however, requires the fusion method to eliminate sample heterogeneity, such as grain size and mineralogical effects. The conventional fusion method has been primarily used for the determination of major elements in silicate rock because dilution by flux significantly reduces sensitivity to trace elements. Because the pressed powder method typically employed for trace element analysis is relatively inefficient and time-consuming, however, a low dilution fusion method was developed. The low dilution fusion bead technique is designed to improve sensitivity for trace elements. This advanced method of determining the chemi
