For geochemical and compositional analysis, the Lab uses a new Bruker Tracer III-SD portable XRF. This instrument allows us to conduct non-destructive surface analysis of ancient materials. While traditionally this approach has been used to assess obsidian, metals, and ceramics, group members are currently investigating is applicability for ancient human hard and soft tissue. The Lab has the capacity to assay materials on a fee-per-sample basis. Contact us to inquire.
