Mobile Solution for Fast Element Mapping

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.

可以在任何方向上设置有或没有支撑手推车的机动框架,也可以轻松拆除运输。通过将测量头安装在轻型三脚架上,可以将Bruker Crono变成便携式点XRF光谱仪。因此,布鲁克·克罗诺(Bruker Crono)是现场测量的理想选择。

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?"
在艺术和保护以及身份验证方面,这些问题是焦点。但是该原理不仅限于绘画。X射线荧光(XRF)分析揭示了有关所有类型艺术品(文化遗产的物体)制造起源的详细信息。

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.
