The Bruker CRONO is easy to operate and reveals the crucial secrets of the object at which it is aimed. The optimal focus distance of 5 – 7 mm from the sample allows for non-contact measurement and is non-invasive and completely non-destructive. No sample preparation is required. Almost flat areas as large as 600 mm by 450 mm can be scanned.

The motorized frame can be setup with or without the support trolley in any orientation or easily be dismantled for transportation. The Bruker CRONO can be turned into a portable spot XRF spectrometer by installing the measurement head on a light tripod. Therefore the Bruker CRONO is ideal for on-site measurements.

High resolution optical images are recorded with an internal camera for each data point in addition to the XRF data. The Bruker CRONO can be equipped to with a He purging system to extend the range of detectable elements as far as Na (Z = 11) to U (Z = 92). The Bruker CRONO micro-XRF spectrometer is equipped with several X-ray filters to optimize the excitation conditions for specific applications.

A spectrum or a map can be recorded with the CRONO software. The automatic peak ID provides a quick visual indication of elements in a sample. The interface shows the spectrum and the element concentration while the acquisition is running. Data interpretation is easy with the overlay of the optical images and the XRF data.
The powerful data processing software ESPRIT Reveal offers many options for the offline analysis. No instrument connection is required for post-processing.

Why do I need a CRONO?

"What is the composition of the paint? Is the paint typical for the artist or this epoch? Is there another layer of paint hidden below the surface?"
These questions are in the spotlight when it comes to art and conservation, as well as authentication. But the principle is not limited to paintings. Details on the origin of manufacturing of all types of artwork (objects of cultural heritage) are revealed by x-ray fluorescence (XRF) analysis a completely non-destructive method.

The Bruker CRONO is an open beam system for point measurements or area scans to retrieve the distribution of multiple elements at the same time. Objects as large as 600 mm by 450 mm can be scanned in a single mesurement. Larger areas can be scanned in multiple mesurements. Recording the XRF spectrum on an area this large is also termed macro-XRF or MA-XRF.

For the analysis of the local distribution of elements transportation of valuable artwork such as paintings or historic artifacts to the laboratory can be avoided. The Bruker CRONO is a mobile micro-XRF spectrometer.
