Spike recovery analytical chemistry

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. WebAug 1, 2024 · Filter blank: A very specific type of blank where the blank solution is filtered through the same apparatus used in processing authentic samples. Fortified method blank: This type of method blank (see below) is spiked with analyte. Not to be confused with spike samples, used to determine analyte recovery, fortified method blanks are used to assess …
