Control samples of known composition. LCS and Method Spike <br /> data are used to validate batch analytical results. <br /> Matrix Spike(s): Aliquot of a sample (aqueous or solid) with added quantities of specific compounds and <br /> subjected to the entire analytical procedure. Matrix spike and matrix spike duplicate QC data are advisory. <br /> ' Method Stank: An analytical control consisting of all reagents, internal standards, and surrogate standards <br /> carried through the entire analytical process. Used to monitor Laboratory background and reagent contamination. <br /> ' Not Detected (ND): Nat detected at or above the reporting Limit. <br /> Relative Percent Difference (RPD): An indication of method precision based on duplicate analysis. <br /> Reporting Limit (RL): The lowest concentration routinely determined during laboratory operations. The RL is <br /> generally 1 to 10 times the Method Detection Limit (MDL). Reporting limits are matrix, method, and analyte <br /> dependent and take into-account any dilutions performed as part of the analysis. — <br /> Surrogates: Organic compounds which are simitar to analytes of interest in chemical behavior, but are not found <br /> in environmental samples. Surrogates are added to At blanks, calibration and check standards, samples, and <br /> spiked samples. Surrogate recovery is monitored as an indication of acceptable sample preparation and <br /> instrumental performance. <br /> D: Surrogates diluted out. <br /> Indicates result outside of established laboratory OC Limits. <br />
