值得了解

Founded in 1999 by Bear and Cara Williams. The current site names no report products and gives no address, so no city is recorded. It lists instrumentation including ED-XRF, FTIR, Raman and UV-Vis-NIR and describes these as aiding geographic origin work, but it does not state that the laboratory issues country-of-origin opinions. Report queries go through an enquiry form rather than an online lookup.
