| Abstract: | This article discusses the synthetic method of reference materials for in situ microprobe analysis of major and trace elements by using high-temperature furnace.We select basalt reference material GBW07105(GSR-3) for high temperature fusion,quenching research to obtain basalt glass,which provides a reference synthetic method for other geological standard reference materials for microprobe analysis.Forty-six major and trace elements were analyzed by laser ablation-quadrupole inductively coupled plasma mass spectrometer(LA-Q-ICPMS).The results show that major and trace elements of the basalt glass have good precision and accuracy in microprobe analysis,which are better than 10%.So the basalt glass can be used as an intralab standard material in microprobe analysis.In 36 trace elements,the relative deviations of measured values obtained by LA-Q-ICPMS from the reference values obtained by chemical method are generally better than 10%.The standard values of some elements in GSR-3 are supposed to be amended based on this study. |
