X-ray fluorescence (XRF) is a fast and non-destructive method for analyzing the elemental composition of materials. In our research, we use X-MET 8000 portable analyzer, which enables precise determination of elemental content without the need for sample preparation. The device allows for measurements to be taken directly in the field, providing reliable results in just a few seconds. The XRF method is used in applications such as the analysis of metals and alloys, industrial materials, waste, and in quality control and material identification.
