Recovery of the analyte over the entire analytical process is determined from matrix spikes, spiked blanks, and surrogate spikes. ... The spiked method blank is a separate aliquot of the same reagent water used for the method blank that is spiked with the compound of interest at a concentration as close as possible to the concentration of the mid-level calibration standard. 1, record 1, English, - spiked%20method%20blank

Le taux de récupération d’une substance à analyser au cours de l'ensemble du processus d’analyse est déterminé à partir d’échantillons de matrice et de blancs enrichis avec des concentrations connues de la substance à analyser et d’analogues. [...] Un blanc de méthode enrichi est une fraction de la même eau que celle utilisée pour le blanc de méthode à laquelle on ajoute la substance à analyser à une concentration aussi proche que possible de celle de l'étalon de concentration intermédiaire. 1, record 1, French, - blanc%20de%20m%C3%A9thode%20enrichi
