Spectrophotometric Techniques Used In The Prescreening Stage Of Radiocarbon Dating Process

The characterization of samples by spectrophotometric methods, before radiocarbon dating using 1 MV HVEE Tandetron (TM) accelerator, may offer additional information in establishing the age of museum materials being contaminated with preserving agents, and of archaeological materials contaminated with exogenous carbon in the post-depositional stage. Macromolecular structures can be determined using FTIR/FT-Raman techniques. Old samples against modern ones may be compared, highlighting the impact of spectrophotometric methods results on radiocarbon dating estimates using AMS. The review of the possibilities of multidisciplinary analysis was done using some examples. The femtogram level reached in AMS measurements represents a strong reason to optimize the FTIR/FT-Raman analyses, in a future research.
