ACZ Laboratories, Inc. <br />2773 Downhill Drive Steamboat Springs. CO 80487 (800) 334-5493 <br />Batch A distinct set of samples analyzed at a specific time <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 manufacturer's certificate of analysis <br />PQL Practical Quantitation Limit, typically 5 times the MDL. <br />QC True Value of the Control Sample or the amount added to the Spike <br />Rec Amount of the true value or spike added recovered, in % (except for LCSS, mg/Kg) <br />RPD Relative Percent Difference, calculation used for Duplicate QC Types <br />Upper Upper Recovery Limit, in % (except for LCSS, mg/Kg) <br />Sample Value of the Sample of interest <br />xTze'^ <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 Fortified Matrix <br />CCV Continuing Calivation Verification standard LFMD Laboratory Fortified Matrix Duplicate <br />DUP Sample Duplicate LRB Laboratory Reagent Blank <br />/CB Initial Calibration Blank MS Matrix Spike <br />ICV Initial Calibration Verification 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 PQV Practical Quantitation Verification standard <br />LCSW laboratory Control Sample -Water SDL Serial Dilution <br />• <br />Blanks Verifies 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 prep procedure. <br />Duplicates Verifies the precision of the instrument and/or method. <br />Spikes/Fortified Matrix Determines sample matrix interferences, if any. <br />Standard Verifies the validity of the calibration. <br />a ~ . <br />B Analyte concentration detected at a value between MDL and PQL. <br />H Analysis exceeded method hold time. pH is a field 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 bequse 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 data accepted 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 Quality control sample is out of control. <br />Z Poor spike recovery is accepted because sample concentration is four times greater than spike concentration. <br />r~ - - - - <br />(1) EPA 600/4-83-020.
