An important acquisition for the XRF laboratory

03.03.2022

Micro-XRF (X-ray fluorescence) spectrometry is imaging technique which enables localization of elements in different solid samples: biological tissues, geological materials, metals, cultural heritage artefacts. Our XRF laboratory (Laboratory for X-ray fluorescence spectrometry) is now equipped with the state of the art micro-XRF analytical microscope XGT-9000, enabling the team to scan samples sized from few mm up to  15 cm. The first measurements were successfully performed:
