Semiempirical approach for standardless calibration in µ-XRF spectrometry using capillary lenses

Quantitative µ‐XRF analysis based on standardless calibration is limited by the lack of information on the shape of the excitation spectrum resulting from using capillary lenses. The measurement of radiation scattered from a sample was used in combination with Monte Carlo simulation of radiation tra...

Summary:Quantitative µ‐XRF analysis based on standardless calibration is limited by the lack of information on the shape of the excitation spectrum resulting from using capillary lenses. The measurement of radiation scattered from a sample was used in combination with Monte Carlo simulation of radiation transport to estimate the energy spectral distribution of the excitation radiation. Further, a standardless calibration based on the fundamental parameter method implemented in the IAEA‐QXAS software package was carried out and verified for glass and fused ore certified reference materials. The accuracy and repeatability achieved are reported. Copyright © 2004 John Wiley & Sons, Ltd.
