Abstract
Cilj ovog rada je dati literaturni pregled razvoja i validacije metode određivanja metala u uljima valno disperzivnom spektrometrijom (eng. wavelength dispersive X-ray fluorescence, WDXRF). Rendgenska fluorescencijska spektrometrija ( eng. X-ray fluorescence, XRF) je nedestruktivna, brza, univerzalna i relativno jednostavna analitička metoda za određivanje elementnog sastava plinovitih, tekućih i krutih uzoraka uz minimalnu pripravu. Dva su načina detekcije fluorescentnih rendgenskih zraka: valno disperzivna detekcija (WDXRF) i energetski disperzivna detekcija (eng. energy dispersive X-ray fluorescence, EDXRF). WDXRF se najčešće koristi za rutinska određivanja, kada je potrebna brza i točna analiza, ali bez potrebe za fleksibilnošću. To je analitička metoda koja osigurava dovoljno visoku preciznost, razlučivost i osjetljivost. WDXRF spektrometrija našla je široku primjenu u rutinskim više elementnim analizama različitih uzoraka od mineralnih sirovina i gotovih proizvoda, arheoloških materijala do farmaceutskih proizvoda, za određivanje sumpora u najrazličitijim uzorcima te u kontroli kvalitete (za određivanje Na, Mg, P, Cl, K, Ca, Fe i Zn).
Abstract (english)
The main purpose of this paper is to provide a literature preview of the development and validation of methods for determination of metals in oils by wavelength dispersive X-ray spectrometry (WDXRF). X-ray fluorescence spectrometry (XRF) is a non-destructive, fast, universal and simple analytical method for the determination of the elemental composition of gaseous, liquid and solid samples with minimal sample preparation. There are two ways to detect fluorescent X-rays: wavelength dispersive detection (WDXRF) and energy dispersive detection (EDXRF). WDXRF is mostly used for routine determination when a fast and accurate analysis is required, without the need for flexibility. This analytical method offers highly enough precision, resolution and sensitivity. WDXRF has been widely used in multi-elemental routine analysis of different samples such as mineral raw materials and finished products, archeological materials, pharmaceutical products, for the determination of sulphur in various samples as well as in quality control (for preparation Na, Mg, P, Cl, K, Ca, Fe and Zn).
