X-ray Fluorescence (XRF) Spectroscopy

The handheld XRF can be used for in situ non-destructive elemental analysis. It is complementary to Raman spectroscopy and reflectance spectroscopy obtained from spectral imaging or FORS.

Applications:

  • Assistance in identification inorganic pigments

  • Examination of the elemental composition of glass.

X-ray Fluorescence (XRF) Scanning

Our lab offers the ability of in-situ XRF scanning of cultural heritage objects. Our macro-XRF scanner is an in-house developed system that interfaces a portable Niton XRF with an X-Y motorised translation stage (max. area 15x15 cm2) that automatically scans and produces an XRF spectral image cube with spatial resolution of 3mm and scanning speed up to ~0.1 mm/s limited by the XRF sensitivity.
