Matrix Spike Duplicate/Recovery Summary Representative compounds lor each traction are spiked Into allquots ol samples selected lor spiking. The recoveries and precision lor these spiked compounds are calculated and reported on the EPA-deslgnated form, Corrections are made for dilutions and for non- standard sample sizes, An additional column has been added to the iiPA form to Include concentrations ol spike compounds In original, unsplked, samples; these are subtracted Irom the concentrations detected In the spiked samples, Associated samples are listed lor each spiked set ot sample fractions; these represent samples processed with the spiked set, at the frequency of one set for each fraction per case, or at least per 20 samples.
