röntgenülekanded

Röntgenülekanded, also known as X-ray fluorescence (XRF) analysis, is a non-destructive analytical technique used for determining the elemental composition of a sample. This method relies on the principle that when a sample is bombarded with X-rays, the atoms within the sample emit characteristic fluorescent X-rays. These emitted X-rays have specific energies, or wavelengths, that are unique to each element present. By measuring the energy and intensity of these fluorescent X-rays, one can identify and quantify the elements in the sample.

The process typically involves an X-ray source that generates primary X-rays. These primary X-rays strike the sample, causing inner-shell electrons of the atoms to be ejected. As outer-shell electrons fall to fill these vacancies, they release energy in the form of fluorescent X-rays. A detector then collects these emitted X-rays and converts them into an electrical signal. Sophisticated software analyzes this signal to produce a spectrum that shows the different elemental peaks. The position of a peak on the spectrum indicates the element, while the height of the peak is proportional to the concentration of that element.

Röntgenülekanded is widely used across various fields, including geology, materials science, environmental monitoring, and industrial quality control, due to its speed, sensitivity, and ability to analyze solid, liquid, and powder samples with minimal preparation. It can detect elements from sodium up to uranium in the periodic table.
