Webb7. Calculate % Recovery. If the concentration of the spiked sample is found to be 2.24 mg/L, %R = (2.24 mg/L spiked result – 1.22 mg/L unspiked result) / 1 mg/L known spike added concentration (see . Note. below) = 102.0 %R . 8. Compare the %R to the published analytical method criteria or the laboratory SOP criteria to determine if the ...

WebbBias is 100 minus the recovery, RSD2/n is the uncertainty of the bias, n is the number of recoveries included in the bias and 2 is the coverage factor corresponding to 95% confidence level. If the expanded uncertainty is higher than 50%, the analytical results must be corrected for recovery and the combined uncertainty is then given by: Uc = Webbadded to this sample, and a recovery test was conducted. The recovery rate was 93 %, with good overall results. In Figure 4, excellent linearity is demonstrated using malic acid over …
