ACZ Laboratories, Inc. <br />2773 Downhill Drive Steamboat Springs, CO 80487 <br />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 Recovered amount of the true value or spike added, 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 />m <br />AS <br />Analytical Spike (Post Digestion) <br />LCSWD <br />Laboratory Control Sample - Water Duplicate <br />ASD <br />Analytical Spike (Post Digestion) Duplicate <br />LFB <br />Laboratory Fortified Blank <br />CCB <br />Continuing Calibration Blank <br />LFM <br />Laboratory Fortified Matrix <br />CCV <br />Continuing Calibration Verification standard <br />LFMD <br />Laboratory Fortified Matrix Duplicate <br />OUP <br />Sample Duplicate <br />LRB <br />Laboratory Reagent Blank <br />ICB <br />Initial Calibration Blank <br />MS <br />Matra Spike <br />ICV <br />Initial Calibration Verification standard <br />MSD <br />Matra Spike Duplicate <br />ICSAB <br />Inter - element Correction Standard - A plus B solutions <br />PBS <br />Prep Blank - Sod <br />LCSS <br />Laboratory Control Sample - Sal <br />PBW <br />Prep Blank - Water <br />LCSSD <br />Laboratory Control Sample - Sol Duplicate <br />PQV <br />Practical Quantitation Verification standard <br />LCSW <br />Laboratory Control Sample - Water <br />SDL <br />Serial Dilution <br />M <br />Blanks <br />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 <br />Verifies the precision of the instrument and /or method. <br />Spikes/Fortified Matra Determines sample matrix interferences, if any. <br />Standard <br />Verifies the validity of the calibration <br />B Analyte concentration detected at a value between MDL and PQL. The associated value is an estimated quantity <br />H Analysis exceeded method hold time. pH is a field test with an immediate hold time. <br />L Target anayte response was below the laboratory defined negative threshold. <br />U The material was analyzed for, but was not detected above the level of the associated value. <br />The associated value is either the sample quantitation limit or the sample detection limit. <br />(1) QC results calculated from raw data. Results may vary slightly if the rounded values are used in the calculations. <br />(2) Soil, Sludge, and Plant matrices for Inorganic analyses are reported on a dry weight basis. <br />(3) Animal matrices for Inorganic analyses are reported on an "as received" basis. <br />(4) An asterisk in the "XQ" column indicates there is an extended qualifier and /or certification qualifier <br />associated with the result. <br />(5) If the MDL equals the POL or the MDL column is omitted, the PQL is the reporting limit. <br />For a complete list of ACZ s Extended Qualifiers, please click: htIp:%% ryww_ acr_comlpuhliC /Crtc1uallitit.pdf <br />REP001 09 12 01 <br />Page 11 of 32 <br />
