An innovative multi-analytical strategy to assess the presence of fossil hydrocarbons in a mummification balm

This research work focuses on the detection of radiocarbon contamination, for instance bitumen, in a mummification balm prior to its dating. A new analytical methodology combining ATR-FT-IR (Attenuated Total Reflexion - Fourier Transform Infrared Spectroscopy), TLC (Thin Layer Chromatography), is developed order allow straightforward identification contaminants directly from excavation site and monitor sampling The mummy Padiimenipet, currently held at Louvre Museum, was chosen build as previous relying GC–MS (Gas Chromatography – Mass Spectrometry) identified bitumen this balm. Radiocarbon dating multiple aliquots sample by AMS (Accelerator confirmed presence fossil compounds their important heterogeneity. ATR-FTIR approaches allowed preliminary characterization, with main chemical families notably hydrocarbons. TLC, used normal phase using methanol eluent, very efficient way hydrocarbons such technique could easily be situ select samples devoid these compounds, possibly fossil. analysis requiring specific SPE (solid extraction) concentration but not designed offer an implemented diagnosis. Consequently, combined use future on-site perform screening organic before identify contamination..
