Evaluation of the Element Content in an Automatic Qualitative Analysis of Substances Using a Cross-Correlation Function

Abstract

A method and tools for automated evaluation of the element content in a sample using the only one sample spectrum is presented. The presence of elements in the sample is determined by qualitative cross-correlation analysis with a low probability of false alarm and high performance. The element content is calculated by modified spectral-line detection and enhancement method and adjusted to use in modern automated systems. The tool kit requires tuning to a particular spectral system using previously obtained results of quantitative spectral analysis for this system. The efficiency of the procedure is exemplified in evaluation of the content of matrix elements of geological powder samples of Si, Ti, Al, Mg, Fe, Ca, and Mn using two different analytical spectral systems.
