20.500.12556/DKUM-96182 Priprava vzorcev in uporaba XRF analizatorja za določanje kemijske sestave materialov v energetiki diplomsko delo Sample preparation and application of XRF analysis for determining the chemical composition of materials in energetics Diplomsko delo obravnava pomen kemijske analize pri oceni materialov, ki se uporabljajo v energetiki. Z metodo rentgensko fluorescenčne spektroskopije je bila določena elementarna sestava kovin, izolacijskih materialov in rudnin, s poudarkom na vplivu kemične sestave na zanesljivost energetskih naprav. Rezultati analiz z napravo Niton XL3t GOLDD+ so pokazali, da pravilna priprava vzorcev pomembno izboljša natančnost meritev ter da že majhne razlike v sestavi vplivajo na lastnosti materialov. Prepoznani minerali sfalerit in galenit potrjujejo uporabnost metode tudi pri analizi surovin. The diploma thesis examines the importance of chemical analysis in evaluating materials used in the energy sector. X-ray fluorescence spectroscopy was applied to determine the elemental composition of metals, insulating materials and mineral samples, highlighting the influence of chemical composition on the reliability of energy systems. Results obtained using the Niton XL3t GOLDD+ device show that proper sample preparation significantly improves measurement accuracy and that even small compositional differences affect material properties. The identification of sphalerite and galena further demonstrates the method’s applicability to raw material characterization. kemijska analiza rentgensko fluorescenčna spektroskopija materiali v energetiki kovinski materiali rudnine chemical analysis X-ray fluorescence spectroscopy materials in energy systems metallic materials minerals true true false [B.
