WebSpike Recoveries One of the most important quality assessment tools is the recovery of a known addition, or spike, of analyte to a method blank, field blank, or sample. To determine a spike recovery, the blank or sample is split into two portions, and a known amount of a standard solution of the analyte is added to one portion. WebSpike and recovery is used to determine whether analyte detection is affected by differences in the standard curve diluent and biological sample matrix. Sample matrix is …
