Mobile Large Area Micro-XRF Spectrometer

Designed for in-situ, non-destructive and very fast examination of large objects

CRONO is a mobile and reconfigurable fast micro-XRF scanner for cultural heritage applications. The XRF components are fully integrated into a compact measurement head and allow the detection of 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).

The measurement head is mounted on a motorized stage that enables a scanning area of up to 60 cm x 45 cm. The motorized frame and the support unit can be easily dismounted for transportation. CRONO can be turned into a portable spot XRF device by installing the measurement head on a light tripod.

The instrument works in a complete non-contact mode with an optimum focus distance of 5 - 7 mm from the sample. The analysis area is always under control thanks to several monitoring systems.
