电子探针测试独居石样品中Ce的M能级谱线对F的K能级谱线干扰研究
Interference of the Spectral Line Mζ in the M Energy Level Series of Ce on the F Element Kα Peak in Monazite Samples
摘要
Abstract
Quantitative analysis of the ultra-light element fluorine(F)has always been one of the difficulties in electron probe microanalysis(EPMA).High-resolution qualitative analysis and proper subtraction of spectral interferences from major elements are prerequisites for accurate F quantification.This study focuses on F in monazite samples with very low F content or even close to 0.Through comparison and analysis of high-resolution qualitative analysis spectra with apatite,InP,CeAl2,and LaF3 samples,it is found that the third-order line of high-content P Kα does not interfere with the F Kα peak,but the spectral line Mζ of the M energy level series of Ce interferes with the F Kα peak.Monazite with high Ce content needs accurate quantitative analysis of F through interference peak subtraction.The interference of the M-level spectral lines(including Mα,Mβ,Mζ)of rare earth elements on ultra-light element peaks needs to be taken seriously,and the necessary interference correction should be made through qualitative analysis of the spectra.关键词
