In analytical chemistry recovery is a parameter that indicates the amount of analyte determined by a method of analysis relative to the total quantity. It allows to determine analytical losses during the analytic procedure as well as being a way of expressing accuracy. Determinationsetemodify wikitesto
Recovery is evaluated by measuring analytic concentrations added to real specimens (spiked samples). Recovery (%) = [(C1 - C2) / C3] 100

The more the recovery is close to 100% so the result is good though a 100% recovery does not necessarily indicate the absence of errors. The final result of the analysis can be expressed taking into account the correction made to recovery. You can also get values above 100%.
Usually an analytic method prescribes that you have to fall within a well-defined range of recovery values. Voices correlateemodify wikitesto
