PTS Insight: A Closer Look into Paper – Chemical Paper Analysis by IR and Raman Spectroscopy
Today, the paper industry is confronted with a growing demand for new products using paper and board with enhanced properties and new functionalities. Consequently, paper and board are fast changing and are becoming more complex in composition and structure. They can contain incorporated functional additives, layers or barriers and can be furnished with multi-layered coatings. This complex composition of papers still today presents a great challenge to paper analysis, especially when paper components are present in low concentrations and have to be studied for their microscopic distribution in the paper cross-section.
Infrared (IR) and Raman spectroscopy have great potential for a comprehensive and very specific chemical characterization of paper. Raman microscopy, in particular, offers new possibilities to chemical paper analysis. By using the Raman imaging technique, the presence and distribution of different paper components on the paper surface or along the cross-section, can be visualized with a very high lateral resolution.

During the event different aspects and possibilities of the analysis of paper by IR and Raman spectroscopy will be presented and discussed. The main emphasis will be given to the use of Raman microscopy to analyse the detailed chemical composition and structure of paper and paper products. Furthermore, the use of spectroscopic analyses of documents and works of art on paper for their authentication and the detection of forgeries will be demonstrated.
We look forward to your participation, your questions & the exchange with you.
