Ja. Gasquez et al., CORRECTION OF LINE INTERFERENCE IN X-RAY-FLUORESCENCE TRACE ANALYSIS - APPLICATION TO YTTRIUM DETERMINATION IN SILICATE ROCKS, X-ray spectrometry, 26(5), 1997, pp. 272-274
An empirical method is proposed for the correction of spectral interfe
rence between characteristic lines in XRF. The procedure is based on a
coefficient which includes instrumental parameters and atomic propert
ies and is obtained with the same standards as those used in calibrati
on, This method has shown to be valid in the range of concentration st
udied, The application of the method to the interference of Rb K beta(
1) on Y K alpha in silicate rocks is described, Experimental proof was
demonstrated using Certified Reference Materials (CRMs) and samples a
nalysed in other laboratories. (C) 1997 by John Wiley & Sons, Ltd.
