Calibration of Handheld X-ray Fluorescence Spectrometer for Identification and Semi-quantitative Analysis of Objects with Stratified Structure

Popis výsledku v původním jazyce

The aim of this paper is to introduce an easily feasible procedure for data evaluation in X-ray fluorescence analysis that enables to identify stratified structure of an investigated object and to determine the approximate amount of an element and its mean depth under the surface. This technique is based on a Ka/Kb diagram describing the relation of Kα/Kβ ratio versus Kα count rate for various depth distributions of a certain element. Such calibration was performed for NITON XL3t GOLDD Plus analyzer as a typical example of nowadays very popular handheld analyzers that enable in-situ measurements and have many users worldwide. Ka/Kb diagrams for iron, copper, nickel and titanium were drawn by means of combination of measurements and Monte Carlo simulations and then applied to the determination of approximate structures of several objects. The advantages and also some disadvantages of this technique in connection with the handheld analyzers are summarized in this article.
