Infra-red spectrometry (FTIR)

Fourier Transform Infrared Spectroscopy (FTIR) is a molecular analysis technique which makes it possible to obtain information on the chemical bonds and the molecular structure of the materials which are analysed. It is used to enable the identification of bonding agents (glue, wax, oil..), varnishes, fixing and bonding agents to be found in paintings as well as the identification of certain pigments. It is also used to determine the nature of salts and alteration products.
