Portable devices for infrared and Raman spectroscopy: methodology of their use within non-invasive survey of paintings in situ
Čermáková, Zdeňka ; Košařová, Veronika
Aim of the methodology is to determine the limits of use of currently available portable IR and Raman spectrometers for the analysis of painted artworks, describe the complicating factors during the measurement and especially within the subsequent interpretation of spectra, which is critical for the overall process. As a result, a practical guidance for the inclusion of non-invasive spectroscopic methods to standard survey of paintings is provided. The methodology is focused on easily portable spectrometers which can be introduce for the analysis of cultural heritage objects directly on-site, and which thereby achieve high flexibility of use.

Limitations of spectroscopic methods in the study of earthy pigments
Košařová, V. ; Hradil, David ; Kanický, V.
Nowadays, the spectroscopic methods, above all Infrared Spectroscopy (IR), are the most frequently used analytical methods in the research of cultural heritage, which is mainly caused by easy use and non-invasiveness of these methods and a broad range of their application, which comprises both organic and inorganic substances. Nevertheless, each analytical technique has its detection limits, and the fact that a particular method is suitable for one type of a sample does not automatically mean that it will be appropriate for the identification of another sample. Therefore, the aim of the study is to demonstrate the limitations of both Raman Spectroscopy (RS) and infrared spectroscopy in the study of earthy materials.
