In this project, Total-reflection X-ray fluorescence (TXRF) instrumentation is achieved and installed. This approach allows us to determine the elemental composition of micro-samples and to quantify it. Appart from the analytical instrumentation, equipment fora n appropriate sample preparation is foreseen. The technique allows us to determine simultaneously the main elements as well as the tracé elemental composition. Applications of the approach are amongst others in the field of archaeometry.
