X-ray fluorescence spectrometer

Brand: Bruker Artax

Software: Spectra (Artax) 7.2.5

Capabilities: This is an open-architecture x-ray fluorescence spectrometer (XRF) which is able to perform elemental analysis without contacting an object’s surface. The heavy duty tripod and arm allows the flexible positioning of the analytical head relative to objects. The analytical interface is attached to X-Y-Z motors, which are used to accurately position it with the aid of an on-board camera and laser beam. In addition to point spectra, the instrument is able to collect line scans and 2D elemental maps. The unit can be equipped with a micro-focus Rh anode x-ray tube that produces a 75 µm x-ray beam at the sample surface or a fine-focus W anode x-ray tube that has interchangeable apertures (0.2 mm - 1.5 mm). Compressed helium gas can be used to increase the sensitivity of the unit to light elements. Sodium (Na) is the lightest element that it can detect.

Practical use: This XRF instrument is used to perform non-destructive, in-situ, elemental analysis of objects in Yale’s cultural and natural history collections. While it is capable of quantitative analysis, it is most frequently used to provide qualitative or semi-quantitative information.
