LC-MS and FT-IR characterization of amber artifacts

What is it about?

This work focuses on using analytical methods, such as Fourier transform Infrared spectroscopy (FTIR) and high performance liquid chromatography (HPLC) with mass spectrometry (MS) detection to assess archaeological and geological amber. The proposed LC-MS method was successfully applied for the quantification of succinic acid content both in geological and archaeological samples of amber. The developed FTIR method provided some criteria which is able to differentiate between Baltic and Romanian amber (Romanite) that furthermore validates on archaeological amber artefacts.
