Use of the term "recovery" and "apparent recovery" in analytical procedures (IUPAC Recommendations 2002)

D. T. Burns,* K. Danzer, and A. Townshend

Abstract: The terms recovery and apparent recovery are recommended to avoid confusion caused by the use of the term recovery to cover two distinct situations. These situations deal with: (a) the yield of a preconcentration or extraction stage of an analytical process (where recovery is recommended) and (b) the quantity
observed value/reference value, obtained using an analytical procedure that involves a calibration graph (where apparent recovery is recommended).
