From Banknotes to Diamonds: Applications of Micro Analytical Chemistry in Forensic Science

Gene Hall, Rutgers University, Piscataway, NJ

Counterfeiters have become more sophisticated in making products that can fool the public into thinking that their products are the same as the genuine ones. With this in mind, our laboratory has been using modern state-of-the-art micro analytical techniques to determine the composition and sources of counterfeit products. Specifically, our laboratory is using micro energy dispersive X-ray fluorescence (EDXRF) to determine the elemental content of counterfeit products. This information is supplemented with micro Raman and micro FTIR to determine the molecular content of the counterfeit samples. This meeting will focus on the use of the above micro analytical techniques to characterize banknotes, coins, baseball cards, stock certificates, gemstones, passports, and consumer products into genuine and counterfeit. This was accomplished by analyzing the pigments, paper, inks, and mineral content of the samples. In addition, the source of the counterfeit samples will be revealed and how they were produced. Detailed analytical protocols and data presentation will also be presented along with examples from our personal forensic files.
