DirectAMS processes sample material according to standard operating procedures shown through internal testing and/or published reports to yield reliable data for a given sample type. Upon assessment of the sample material, DirectAMS scientists may reassign a sample to a different type that more closely matches the characteristics of the sample. This may result in higher or lower processing fees. DirectAMS will immediately notify the Submitter for approval to amend the requested service.
