Laboratories, Inc. <br />'773 Downhill Drive Steamboat Sorinas. CO B04A7 /F091 ..?5 <br />Batch A distinct set of samples analyzed at a specifc lime <br />Found Value of the QC Type of interest <br />Limit Upper limit for RPD, in %. <br />Lower Lower Recovery Limit, in % (except for LCSS, mg/Kg) <br />MDL Method Detection Limit. Same as Minimum Reporting Limit. Allows for instrument and annual fluctuations. <br />PCN/SCN A number assigned to reagents/standards to trace to the manufacturers certificate of analysis <br />PDL Practical Cuantitation Limit, typically 6 times the MDL. <br />QC True Value of the Control Sample or the amount added to the Spike <br />Rec Amount of the lme value or spike added recovered, in % (except for LCSS, mg/Kg) <br />RPD Relative Percent Difference, calculation used for Duplicate CC Types <br />Upper Upper Recovery Limit, in % (except for LCSS, mg/Kg) <br />Sample Value of the Sample of interest <br />• <br />a ... _ ~r~m ~ u ... . <br />,, ate'- ~_ _ .. ,...,. . ~,_ <br />5_v .._ <br />.r...~_.,. <br />~~~ ~~ <br />AS Analytical Spike (Post Digestion) LCSWD Laboratory Control Sample -Water Duplicate <br />ASD Analytical Spike (Post Digestion) Duplicate LFB Laboratory Fortified Blank <br />CCB Continuing Calibration Blank LFM Laboratory Fortifed Matrix <br />CCV Continuing Calivation Verification standard LFMD Laboratory Fortifed Matrix Duplicate <br />DUP Sample Duplicate LRB Laboratory Reagent Blank <br />ICB Initial Calibration Blank MS Matrix Spike <br />/CV Initial Calibration Vedfcation standard MSD Matrix Spike Duplicate <br />ICSAB Inter-element Correction Standard - A plus B solutions PBS Prep Blank -Soil <br />LCSS Laboratory Control Sample -Soil PBW Prep Blank -Water <br />LCSSD Laboratory Control Sample -Soil Duplicate PDV Practical Duantitalion Verification standard <br />LCSW Laboratory Control Samplo -Water SDL Serial Dilution <br />sav~=r <br />Blanks Vedfes that there is no or minimal contamination in the prep method or calibration procedure. <br />Control Samples Verifies the accuracy of the method, including the Drep procedure. <br />Duplicates Verifies the precision of the instrument and/or method. <br />Spikes/Fortifed Matdx Determines sample matrix interferences, if any. <br />Standard Verifies the validity of the calibration. <br />B Analyte concentration detected al a value between MDL and PQL. <br />H Analysis exceeded method hold time. pH is a fieltl test with an immediate hold time. <br />R Poor spike recovery accepted because the other spike in the set fell within the given limits. <br />T High Relative Percent Difference (RPD) accepted because sample concentrations are less than 10x the MDL. <br />U Analyte was analyzed for but not detected at the indicated MDL <br />V High blank tlafa acceptetl because sample concentration is 10 times higher than blank concentration <br />W Poor recovery for Silver quality control is accepted because Silver often precipitates with Chloride. <br />X Duality control sample is out of control. <br />Z Poor spike recovery is accepted because sample concentration is four times greater than spike concentration. <br />(1) EPA 600/4-83-020.
