Title: Uncertainty of Integrated Intensity Following Line Profile Fitting of Multiline Spectra

Abstract

A novel method of determining the total uncertainty in the integrated intensity of fitted emission lines in multi-peaked emission spectra is presented. The proposed method does not require an assumption of the type of line profile to be specified. The absolute difference between a fit and measured spectrum defines the uncertainty of the integrated signal intensity and is subsequently decomposed to determine the uncertainty of each peak in multi-line fits. Decomposition relies on tabulating a weighting factor which describes how each peak contributes to the total integral uncertainty. Applications of this method to quantitative approaches in laser-induced breakdown spectroscopy analysis are described.
