/'f~~ Laboratories, Inc. <br />'773 Downhill Ddve Steamboat Sodnas. CO 80487 (800) 3345493 <br />,Batch A distinct set of samples analyzed at a specifc time <br />Found Value of the DC 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 Vace to the manufacturer's certifcate of analysis <br />PDL Practical Quantitation Limit, typically 5 times the MDL. <br />OC True Value of the Control Sample or the amount added to [he Spike <br />Rec Amount of the true value or spike added recovered, in % (except for LCSS, mgMg) <br />RPD Relative Percent Difference, calculation used for Duplicate OC Types <br />Upper Upper Recovery Limit, in % (except for LCSS, mgMg) <br />Sample Value of the Sample of interest <br />AS Analytical Spike (Post Digestion) LCSWD Laboratory Control Sample -Water Duplicate <br />ASD Analytical Spike (Post Digestion) Duplicate LFB Laboratory Fortifed Blank <br />CCB Continuing Calibration Blank LFM Laboratory Fortified Matrix <br />CCV Continuing Calivation Verification standard LFMD Laboratory Fortifed Matrix Duplicate <br />DUP Sample Duplicate LRB Laboratory Reagent Blank <br />/CB Initial Calibration Blank MS MaViz Spike <br />ICV Initial Calibration Verifcation Standard MSD Matdz 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 POV Practical Quantitation Verification standard <br />LCSW Laboratory Control Sample -Water SDL Serial Dilution <br />Blanks Verifies that there is no or minimal contamination in the prep method or calibration procedure. <br />Control Sa mples Verifies Ne accuracy of the method, including th e prep procedure. <br />Duplicates Verifies [he precision of the instrument and/or method. <br />Spikes/Fortifed Matrix Determines sample matrix interterences, 'rf any. <br />Standard Verifies the validity of the calibration. <br />B Analyte concentration detected at a value between MDL and POL. <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 wkhin 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 deteced at the indicated MDL <br />V High blank data accepted because sample mncentretion is 10 times higher than blank concentration <br />W Poor recevery 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 wncentration. <br />(1) EPA 600/4-83-020.
