摘要
Unknown samples are compared to only one standard of similar type; their compositions are calculated from ratios of X-ray line intensities and equations obtained by derivation of the well known Lachance and Traill, Rasberry and Heinrich, and Claisse and Quintin relations. Corrections for matrix effects are small, to the extent that several correction terms can often be omitted. The method probably leads to the ultimate accuracy that can be reached in XRF analysis. © 1979, American Chemical Society. All rights reserved.
