摘要
To avoid of selecting an expensive and unavailable method for analyzing geological and mineral samples such as Inductively Coupled Plasma (ICP), Instrumental Neutron Activation Analysis (INAA), Electron Probe Micro-analyzer (EPMA) and etc. which waste the time and money we try to set an simple and fast analytical standard for X-ray Fluorescence Spectrometry (XRF). To get standards representative of the mineral samples, we select 15 typical samples from granitic rocks of Malayer granitoid complex Western Iran, separate their biotites, analyze them using repand use them as new standards. It is the only way to eliminate the matrix and other physical effects. The separated minerals are assessed as candidates for reference materials for major-element composition. These minerals are analyzed by ICP method in AMEDL laboratories, Australia and results are used for construction of calibration curves to XRF method at the Tarbiat Moallem University of Tehran in order to assess their performance as reference materials. Exactly the same samples are analyzed using new application by XRF. The results are very similar to those for ICP and demonstrated that this simple technic is effective. © 2008 Asian Network for Scientific Information.
