Miami-based Beta Analytic is an ISO 17025-accredited radiocarbon dating and stable isotope laboratory. Subsidiary Isobar Science provides uranium-thorium dating, strontium analysis and geochemical fingerprinting services, among others. The company specializes in isotope ratios using wet chemistry and (LA-)MC-ICP-MS. This presentation will focus on dating bone samples through radiocarbon dating and U-Th dating methods. This includes information on quality factors such as selecting optimal bone sample types and methods of sample preparation for analysis. The presentation will discuss marine reservoir effects, diagenesis and other common issues. Furthermore, there will be a focus on isotopic studies (e.g. carbon, nitrogen, oxygen, strontium, and lead isotopes) and applications including migration studies and dietary reconstructions. Lastly, we will discuss recommendations on how to best select and prepare samples for analysis.

Note: This webinar will occur on Eastern Time
