Booking of the XRF Spectroscope
The Orbis PC Micro EDXRF analyzer system is equipped with a Rh micro-focus X-ray tube (50kV and 1mA) and X-ray multiple Optic turret with 30um poly-capillary X-Ray optics, 1mm and 2mm collimators. The detector is an Apollo XRF-ML50 Silicon Drift Detector with an energy resolution lower than 135eV at the Mn Kalpha. Limit of detection can be as low as few ppm but it depends on the element and the matrix. The sample chamber (D: 360 mm, L: 310 mm) is equipped with a high precision XYZ sample stage (travel 100mm x 100mm x 100mm) which allows chemical mapping and line scans.

This contour plot analysis (Matlab) delves into the composition of a concrete sample from EPFL dating back to 1990. The concrete composition is a critical aspect of its structural integrity and durability, making such analyses invaluable for understanding its properties.
