Theoretical Studies in EDXRF on a New Linear Relation: In(Fluorescent Intensity Ratio of Analyte to Pure Analyte/Concentration of Analyte) versus In(Fluorescent Energy)

Abstract

The inaccuracies and validity of the approximate linear relation between In(fluorescent intensity/concentration) and In(fluorescent energy) are presented and discussed. We then present the derivation of a new linear relation between In(fluorescent intensity ratio of analyte to pure analyte/concentration of analyte) and In(fluorescent energy) which is valid for all elements that can be excited by radiation sources, whether by tube x-ray or by radioisotope sources.
