Portable Small Spot Micro-XRF Elemental Analysis
The Bruker ELIO is a compact, portable energy dispersive X-ray fluorescence spectrometer for elemental analysis. It is non-contact and non-destructive, and therefore ideal for works of art and historical or valuable objects.
- Acquire elemental distribution maps of large objects
- Spectrum and the element concentration displayed during acquisition
- Measure light and heavy elements
- Very fast analysis with excellent energy resolution
- 1mm spot size for high resolution
- Various filters for detecting trace elements at ppm level
Compact and Portable
The measurement head is mounted on a lightweight aluminum tripod and weighs just 2.1 kg. Various tripods are available for different situations. There’s also a motorised XY stage (optional) for acquiring maps up to to 10cm x 10cm.

Cultural Heritage Applications
ELIO is designed for use by conservation scientists in museums, research institutes and universities for analysing artwork, cultural and historical artefacts. Determine the material, chemical and technical aspects of cultural objects for preservation and research purposes.
Generate qualitative, semi-quantitative, comparative and elemental distribution maps from a wide range of types of materials.
In the example below, the elemental distribution maps reveal hidden details on a manuscript from the 15th century. The Pb Ma surface and Pb La/Ma ratio maps reveal a lion on the coat of arms, which was afterwards painted over with an inverted “V” (from Mosca, S., Frizzi, T., Comelli, D. “Illuminated Manuscript”, Microchem Journal 2016, Vol. 124, 775-784).
Portable Mapping and Spectroscopy
ELIO is the only truly portable industrial mapping system. Choose between Mapping and Spot Analysis modes.
Acquire maps of up to 10 cm x 10 cm, using the full energy range to detect both light and heavy elements. An image is stored for every pixel, so you can back-trace your data easily.
The mapping software is easy to use, with features for image processing. Elemental maps can be overlaid with an optical image for your reference. Before starting the analysis, the estimated completion time is displayed for you.
The 1 mm spot size gives you high resolution with a level of detail ideal for the feature size of works of art and historical documents.
There’s an integrated microscope camera, and you can also connect two video cameras. LEDs illuminate the sample, with alignment lasers to help with positioning and identifying the measurement point. These also ensure a safe distance is maintained between the sample and the measurement head.
