The application of the derivative IR-spectroscopy and HPLC–ESI-MS/MS in the analysis of archaeology resin

The applicability of the reducing-difference procedure for the interpretation of the conventional IR-spectroscopy as successful scientific technique for the analysis of ancient and modern resins has been demonstrated. The new temperature tool for modeling of the ancient resin samples has also been shown. The experimental infrared data are supported by the hydride approach of HPLC–MS–MS with ES-ionisation.
