This is the same location used to provide material for AGV-1. Element concentrations for AGV-2 were obtained through a round robin study involving 23 international laboratories. Element concentrations are recommended, if results from three of more independent laboratories using three or more independent analytical procedures are in statistical agreement. Information values with standard deviations are reported when three or more independent laboratories using at least two independent analytical procedures have provided information. Information values without standard deviations represent information from a single laboratory or analytical procedure.
All isotopic information is from a single laboratory.
