AbstractThis 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 main goal of this study is to apply the previously developed and optimized analytical methods in verifying criteria to ascribe and characterize the origin of materials found in archaeological sites. The proposed LC-MS method was successfully applied for the quantification of succinic acid content both in geological and archaeological samples of amber and offers excellent linearity between 0.1 and 5µg mL−1. 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.

AbstractLignocellulosic biomass is considered an attractive and most abundant renewable carbon feedstock. Hydroxymethylfurfural (HMF) is one of the platform molecules obtained from biomass. HMF transformation in the reductive atmosphere allows to obtain numerous value-added molecules with applications in several recently emerged sectors, e.g. biofuels and biopolymers. This process is still intensively investigated, and more efficient, stable and sustainable solutions are envisaged. Therefore, the choice of efficient analytical methods is of great importance. This review covers the methodologies used for the analysis of HMF hydrodeoxygenation, including chromatographic and spectrometric methods. Techniques such as gas chromatography, high-performance liquid chromatography, Fourier transform infrared spectroscopy, nuclear magnetic resonance, and mass spectrometry are mentioned as well in this review.
