XRF and Raman Spectroscopy for Forensics Analysis

|   Seminar/Webinar

Event

Beginning: 06/16/20

Micro-XRF was recently introduced to the field of forensic science for trace analysis, border security, art conservation, and archeology, to name a few. XRF analysis provides rapid and non-destructive analysis of the elemental composition of any material for elements starting from fluorine to Americium. A number of micro-XRF applications including glass and sand analysis, and counterfeit pharmaceutical and consumer products will be presented.

Another technique, Raman spectroscopy, has also been recognized to have the potential to solve a variety of problems in forensic science. Applications, including the identification of fiber, glitter and drugs in containers, will be presented. Raman analysis of cocaine HCl and crack (free base) within a plastic bag or vial, will also be illustrated. Finally, this webinar will present the use of Raman for identifying a variety of polymers used in fibers. We will show "fingerprints" of Kevlar, polystyrene, PET, polypropylene, and others along with different types of Nylon, such as nylon 6, nylon 66, and nylon 12, etc. Using Confocal Raman Microscopy, the fibers were identified while embedded in epoxy.
