XRFmenetelmällä

XRFmenetelmällä refers to the Finnish term for "by means of XRF" or "using the XRF method". XRF is the abbreviation for X-ray fluorescence. X-ray fluorescence is a technique used for elemental analysis. In this method, a sample is bombarded with X-rays, causing the atoms in the sample to emit secondary X-rays at characteristic energies. These emitted X-rays, or fluorescence, are then detected and analyzed. The energy of the fluorescent X-rays is specific to each element, allowing for the identification of the elements present in the sample. The intensity of the fluorescent X-rays is proportional to the concentration of the element, enabling quantitative analysis. XRF is a non-destructive technique, meaning the sample is not altered or damaged during the analysis. It can be used to analyze a wide range of solid, liquid, and powder samples. Common applications include material identification, quality control, environmental monitoring, and research in fields such as geology, metallurgy, and art conservation. The phrase XRFmenetelmällä emphasizes the application of this specific analytical technique to achieve a particular outcome or obtain certain information about a sample.
