Could you please provide detailed instructions on, or point me to the appropriate website for the following tasks?
(1) analytical requirements for the qualification of secondary reference standard material (I am looking for details beyond "compare the 2' to the 1' source" - I am interested in finding out about testing requirements such as how many assay replicates are required, what testing is required beyond assay, etc.)
and
(2) analytical elements of conducting a column equivalency study
Many thanks!
