摘要: Portable X-ray Fluorescence Spectrometer (PXRF) is a qualitative and semi-quantitative elemental analysis method. Recently, many researches using PXRF in the of materials have been reported. However, has not extensively applied forensic science, thus this study devoted to demonstrate utility technique through rapid glass samples for preliminary discrimination. Major elements such as Si, O, Ca, Al, Na, well traces Sr, Rb, K, Fe Sn, 25 were analyzed by PXRF. The amounts some elements, Fe, Zr, vary different samples, while other Th, are consistent most tested samples. results show that we can discriminate 98.31 % 7,500 pair-wise comparisons created from This establishes new method glass, which shows potential be further discrimination field.
