ATR-FTIR (Attenuated Total Reflection Fourier Transform Infrared Spectroscopy) is a powerful analytical technique widely used in the examination of artworks and cultural heritage materials. In art investigation, it enables the identification of organic and inorganic compounds based on their characteristic infrared absorption bands, providing molecular-level information with minimal or no sampling. This makes ATR-FTIR Spectroscopy for paper particularly valuable in conservation science, where preserving the integrity of the object is essential.
For historical documents on paper, ATR-FTIR plays a crucial role in characterizing both the support and the materials applied to it. Cellulose, sizing agents, fillers, inks, adhesives, and degradation products each display distinctive spectral features that can be recognized and interpreted. ATR-FTIR Spectroscopy for paper is especially effective for studying paper composition, assessing ageing and oxidation processes, and identifying restoration materials introduced during past conservation treatments.
By allowing rapid, localized analysis directly on the document surface, ATR-FTIR supports informed conservation decisions and enhances our understanding of historical manufacturing techniques. The reliability and versatility of ATR-FTIR Spectroscopy for paper make it a cornerstone method in the scientific examination of paper-based heritage objects.
Learn Technical Photography for Art Examination
Technical Photography is one of the most powerful—and often overlooked—tools for the scientific examination of art and archaeology. If you are a conservator, scientist, or art collector and you are not yet familiar with this method, it is truly a missed opportunity. Using simple, affordable equipment and a clear methodology, Technical Photography allows you to reveal underdrawings, retouchings, material differences, and conservation issues in a completely non-invasive way. Far from being complex or inaccessible, it is an easy entry point into scientific analysis. In many cases, Technical Photography represents the first essential step toward a deeper understanding of artworks and archaeological objects.
