ACZ Laboratories, Inc. <br />773 Downhill Drive Steamboat Samos. CO 80487 (800) 334 <br />Batch A distinct set of samples analyzed at a specific time <br />Found Vakre of the OC Type of interest <br />Lund Upper hmit for RPD, in %. <br />Lower Lower Recovery Limit, in % (except for LCSS, mglKg) <br />LCL Lower Control Limit <br />MDL Method Detection Limit. Same as Minimum Reporting Limit unless omitted or equal to the POL (see comment 94) <br />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. Synonymous with the EPA term "minimum lever. <br />QC Two Vakie of the Control Sample or the amount added to the Spike <br />Roo 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 />UCL Upper Control Limit <br />Sample Value of the Sample of interest <br />SURR <br />Surrogate LFM <br />Laboratory Fortified Matrix <br />INTS <br />Internal Standard LFMD <br />Laboratory Fortified Matrix Duplicate <br />DUP <br />Sample Duplicate LRB <br />Laboratory Reagent Blank <br />LCSS <br />Laboratory Control Sample - Soil MSIMSD <br />Matrix Spike/Matrix Spike Duplicate <br />LCSW <br />Laboratory Control Sample - Water PBS <br />Prep Blank - Soil <br />LFB <br />Laboratory Fortified Blank PBW <br />Prep Blank - Water <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 Matrix Determines sample matrix interferences, if any. <br />B Analyte concentration detected at a value between MDL and POL. The associated value is an estimated quantity. <br />O Analyte concentration is estimated due to result exceeding calibration range. <br />H Analysis exceeded method hold time, pH is a field test with an immediate hold time. <br />J Analyte concentration detected at a value between MDL and POL. The associated value is an estimated quantity. <br />L Target analyte 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) EPA 600/4-83-020.
