Analyzing Art and Historic Artifacts

Analyzing Art and Historic Artifacts with Bruker Instruments

Bruker specializes in both in-situ and advanced lab analysis of art and historical items. With portable systems designed for swift, non-invasive examinations on location, and state-of-the-art lab instruments and microscopes for in-depth studies, Bruker sets the benchmark in art and artifact evaluation.

The ALPHA infrared spectrometer, equipped with a front-facing reflective module, wireless connectivity, and a dedicated portable tripod, provides a convenient solution to assess infrared spectra of large art pieces like murals, typically challenging due to their size or sampling constraints. Complementing this is the BRAVO handheld Raman spectrometer, with its ability to evaluate even the most challenging materials, courtesy of its unique fluorescence mitigation technology. The low-power laser also ensures minimal risk to the samples.

When dealing with detailed analysis of cross-sections or micro-samples, FTIR imaging, and Raman mapping emerge as top choices. Such tools enable users to trace the spatial chemical distribution and ascertain the makeup of individual paint layers, facilitating authenticity checks, and guiding restoration or preservation strategies. For examining larger items, the Senterra II Raman microscope can be set up in a distinct configuration devoid of a sample stage. Furthermore, the LUMOS II FTIR microscope revolutionizes area analysis, boasting an unparalleled spatial resolution that reaches up to 0.5 microns.

Analysis of evidence

Evaluating Forensic Evidence with Bruker Instruments

For forensic evaluations, FTIR and Raman spectroscopy and microscopy have proven invaluable in analyzing evidence materials gathered from crime scenes, such as:

• Textile fibers
• Automotive paint
• Illicit substances
• Document forgeries
• Microparticulates
• Among others…

Understanding the chemical makeup of a material can serve as crucial evidence. Bruker provides a comprehensive range of tools, from portable spectrometers ideal for immediate on-site examinations to high-precision benchtop devices capable of achieving spectral details with a spatial resolution as fine as 0.5 µm.
