Near Infrared Reflectance Spectroscopy for Art Examination parchment

Описание: Art Examination Lab Instruments: Near-Infrared Reflectance Spectroscopy (NIR-RS).
A new series of brief intros to the equipment used in our Art Examination lab.

Near-Infrared (NIR) Reflectance Spectrometer (RS), NIR-RS in the range 930-1690 nm.
This technique involves measuring the reflectance of near-infrared light from a surface, providing valuable information about the composition and structure of the materials being examined.

Advantages of Near-Infrared Reflectance Spectroscopy
1. Non-Destructive: One of the most significant advantages of NIR-RS is that it is non-destructive, meaning that it does not harm the artwork. This is essential for preserving the integrity of valuable and often irreplaceable pieces.
2. In Situ Analysis: NIR-RS can be performed on-site without the need to remove samples from the artwork. Portable NIR-RS instruments allow for analysis in museums, galleries, and other locations where the artworks are displayed or stored.
3. Rapid and Efficient: The technique provides rapid results, allowing for the quick analysis of multiple areas of an artwork. This efficiency is beneficial in large-scale surveys or when time-sensitive decisions are needed in conservation.
4. Complementary Technique: NIR-RS can be used alongside other analytical techniques such as X-ray fluorescence (XRF), Fourier-transform infrared spectroscopy (FTIR), and Raman spectroscopy to provide a comprehensive understanding of an artwork’s composition and structure.
