An analyzed amount, as defined by the United States Environmental Protection Agency via its SEDD Specification Version 5.2, is "the amount (weight or volume) of a sample aliquot, prepared extract, or standard that is used for an analysis." The EPA adds that, "if the analytical method requires the prior use of preparative or cleanup step(s), then [it] is the actual amount of this final extract that is used for the analytical method."
