<br />Laboratory Qualifiers and Definitions
<br />DEFINITIONS:
<br />Accuracy/Bias (% Recovery) - The closeness of agreement between an observed value and an accepted reference value.
<br />Blank (Method/Preparation Blank) -MB/PB - An analyte-free matrix to which all reagents are added in the same volumes/proportions as used In sample
<br />processing. The method blank is used to document contamination resulting from the analytical process.
<br />Duplicate - a field sample and/or laboratory QC sample prepared in duplicate following allot the same processes and procedures used on the original sample
<br />(sample duplicate, LCSD, MSD)
<br />Laboratory Control Sample (LCS ad LCSD) - A known matrix spiked with compounds representative of the target analyte(s). This is used to document
<br />laboratory performance.
<br />Matrix - the component or substrate that contains the analyte of interest (e.g., - groundwater, sediment, soil, waste water, etc)
<br />Matrix Spike (MSIMSD) - Client sample spiked with identical concentrations of target analyte (s). The spiking occurs prior to the sample preparation and
<br />analysis. They are used to document the precision and bias of a method in a given sample matrix.
<br />Method Detection Limit (MDL) - the minimum concentration of a substance that can be measured and reported with a 99% confidence that the analyte
<br />concentration is greater than zero
<br />Practical Ouantitation Limit/Reporting Limit/Limit of Quantitation (PQL/RLJLOQ) - a laboratory determined value at 2 to 5 times above the MIX that can
<br />be reproduced in a manner that results in a 99% confidence level that the result is both accurate and precise. POLs/RLs/LODs reflect all preparation factors
<br />and/or dilution factors that have been applied to the sample during the preparation and/or analytical processes.
<br />Precision (XRPD) - The agreement among a set of replicate/duplicate measurements without regard to known value of the replicates
<br />Surrogate (S) or (Burr) - An organic compound which is similar to the target analyte(s) in chemical composition and behavior In the analytical process, but
<br />which is not normally Mond In environmental samples. Surrogates are used in most organic analysis to demonstrate matrix compatibility with the chosen method
<br />of analysis
<br />Tentatively Identified Compound (TIC) - A compound not contained within the analytical calibration standards but present in the GCMS library of defined
<br />compounds. When the library is searched for an unknown compound, teat frequently give a tentative identification to the compound based on retention time
<br />and primary and secondary ion match. TICs are reported as estimates and are candidates for further investigation.
<br />Units: the unit of measure used to express the reported result - mg/L and mg/Kg (equivalent to PPM - parts per million In liquid and solid), ugIL and rug/Kg
<br />(equivalent to PPB - parts per billion in liquid and solid), ug/m3, mg/m3, ppbv and pprnv (all units of measure for reporting concentrations in air), % (
<br />equivalent to 10000 ppm or 1,000,000 ppb), ug/Wipe ( concentration found on the surface of a single 1,Mpe usually taken over a 100crn2 surface)
<br />LABORATORY QUALIFIERS:
<br />- Indicates when the analyte is found in the associated method or preparation blank
<br />D - Surrogate is not recoverable due to the necessary dilution of the sample
<br />E - Indicates the reportable value is outside of the calibration range of the instrument but within the linear range of the instrument (unless otherwise noted)
<br />Values reported with an E qualifier should be considered as estimated.
<br />H- Indicates that the recommended holding time for the analyte or compound has been exceeded
<br />J- Indicates a value between the method MDL and PQL and that the reported concentration should be considered as estimated rather the quantitative
<br />NA - Not Analyzed
<br />N/A - Not Applicable
<br />ND - Not Detested at a concentration greater than the PQL/RL or, if reported lathe MDL, at greater than the MDL.
<br />NR - Not recoverable - a matrix spike concentration is not recoverable due ton concentration within the original sample that is greater than four times the
<br />spike concentration added
<br />The % RPD between a duplicate scion samples is outside of the absolute values established by laboratory control charts
<br />Spike recovery is outside of established method and/or laboratory control limits. Further explanation of the use of this qualifier should be included within a
<br />case narrative
<br />X -Used to indicate that a value based on pattern identification is within the pattem range but not typical of the pattern found in standards.
<br />Further explanation may or may not be provided within the sample footnote and/or the case narrative.
