The Technical Division of Reference Materials (TDRM) needs volunteers with familiarity of chemical structures to assign InChi key values to analytes in the TDRM RM Database. We are seeking a total of four volunteers who can commit approximately 2-4 hours per month for four months beginning in January. Assigning these values builds the bridge between AOAC and other organizations involved in setting standards associated with measurements, as well as with trade organizations, research and industry. Apply.
