[R1-P-02] Quantitative electron microprobe analysis of xenotime
Keywords:EPMA, Xenotime, Chemical composition, Takehara mine
The conditions suitable for the quantitative analysis of xenotime from the Takehara mine in Mie Prefecture, Japan, using EPMA were investigated. First, a qualitative analysis was performed to identify the major elements and determine the characteristic X-ray positions and the appropriate background measurement positions. In cases where the overlap of peaks was significant, a pulse height analyzer was used when higher-order lines overlapped. An interference correction factor was determined to correct the measured intensity when first-order lines interfered.
