Abstract

HIGHLIGHTS
(1) The interference of the third-order line of P K_α to the F K_α line can be ignored.

(2)The FK_α line and the Ce M_ζ line are seriously overlapped. “Interference Correction” is an effective method.

(3) The interference of the M-level spectral lines (including M_α, M_β, M_ζ) of rare earth elements on the peak of ultralight elements needs to be taken seriously.

ABSTRACT

Quantitative analysis of the ultra-light element F has always been one of the difficulties in electron probe mineral analysis. High-resolution qualitative analysis and the deduction of interference peaks of spectral lines of major elements are the prerequisites for accurate quantitative analysis of F elements. This paper takes F in monazite samples (with very low F content or even close to 0) as the research object. 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 ${\mathrm{P}\;\mathrm{K}}_{\text{α}}$ does not interfere with the $\mathrm{F}\;{\mathrm{K}}_{\text{α}}$ peak, but the spectral line ${\mathbf{M}}_{\text{ζ }}$ of the M energy level series of Ce will interfere with the $\mathrm{F}\;{\mathrm{K}}_{\text{α}}$ peak. Monazite with high Ce content needs accurate quantitative analysis of F through interference peak deduction. The interference of the M-level spectral lines (including ${\mathrm{M}}_{\text{α}}{,\mathrm{M}}_{\text{β }},{\mathrm{M}}_{\text{ζ }}$ ) of rare earth elements on ultra-light element peaks needs to be taken seriously.
