Bruker CRONO

Bruker Small Spot Micro XRF

Bruker CRONO

Mobile, In-Situ Analyser for Large Artworks

The Bruker CRONO is a fast, mobile micro-XRF scanner for cultural heritage (eg artwork and museums). Detect elements in the range from Na to U with good efficiency, even in the energy regions below 2 keV and above 25 keV (e.g. Sn, Sb, and Ba K-edge emissions).

  • Motorised stage for scanning areas up to 60 cm x 45 cm.
  • Frame dismantles easily for transportation.
  • Attach the measurement head to a tripod for portable use.

Safe Analysis of Valuable Objects

Analysis is non-destructive and completely non-contact, with monitoring systems to maintain a safe distance of 1 cm from the surface.

Example Application: Saint Vincent Panels

Micro-XRF was used in a 3 year restoration project on the Saint Vincent Panels (~1450s). Element mapping provided information about the pigments used, and revealed previous restoration efforts. These images were taken using the Bruker Crono.

The Bruker CRONO is a flexible system, which can be reconfigured for measuring different types of artefacts and paintings. The measurement head can be mounted on a trolley so you can tilt the frame from -20° to +90° from horizontal. The motorised frame and trolley can be dismantled easily for transportation.

It can also be converted into a portable scanner, by attaching the measurement head to a tripod. The head weighs only 3kg and measures 28 cm x 15 cm x 15 cm.

Bruker CRONO Configurations

Fast and High Resolution

The excitation source is a highly efficient and compact X-ray generator with Rh anode. You can use different spot sizes, by selecting different collimators in the software (0.5 mm, 1 mm and 2 mm diameter).

There are also 4 software selectable filters, to improve low detection limits for specific applications.


Software is provided for instrument control and monitoring. Spectra and maps are displayed straight away during acquisition. A spectrum is stored for every pixel, giving you comprehensive data. PDF reports can be generated automatically for single measurements and projects.

Element Maps of a Painting

Element maps of a painting (50 cm x 40 cm). Red shows high element concentration, through yellow and green to low concentration in blue. Measurement time ~ 30 min, line speed 20 mm/s, collimator aperture 2 mm, X-ray tube settings 50 kV and 100 µA.
