In the formation of line spectra, line broadening, e.g. Doppler broadening and natural line broadening, might occur causing asymmetric line shape and emission lines“ overlap from various elements. Frequently, the emission line of the element of interest is in close proximity or even overlap-ping with the emission lines from other elements. Two classification tables were developed during this thesis: the emission line table and the interference table. The emission line table serves as the first step in identifying possible emis-sion lines of an element according to their sensitivity. The interference table was created for each emission line listed in the aforementioned table to highlight possible interferences caused by other elements present in the soil sample. In addition to the classification tables, a procedure flow chart was designed as a guideline for users to ensure proper use of elaborated tables during soil sample analysis. Results obtained from the filtering method such as full width at half maximum (FWHM) and symmetry using area comparison proves to be suitable even for Doppler broadening. Identifica-tion of possible interference to a certain distance was decided empirically through emission line graphs comparison while using the FWHM as a factor for the distance range. A threshold of sensitivity difference between the element of interest and possible interfering elements was also established based on an assumption of 10\% interference for each distance range. Tables and flow chart presented in this thesis prove the feasibility of the elaborated method in identifying suitable emission lines for an element during soil sample analysis. Further studies should be performed to test (re)producibility of obtained data.}, language = {en} }
