FRIEDMAN & BRUYA, INC. <br />_________________________________________________ <br />ENVIRONMENTAL CHEMISTS <br /> 8 <br /> <br />Data Qualifiers & Definitions a - The analyte was detected at a level less than five times the reporting limit. The RPD results may not provide reliable information on the variability of the analysis. <br /> b - The analyte was spiked at a level that was less than five times that present in the sample. Matrix spike recoveries may not be meaningful. <br /> ca - The calibration results for the analyte were outside of acceptance criteria, biased low; or, the calibration results for the analyte were outside of acceptance criteria, biased high, with a detection for the analyte in the sample. The value reported is an estimate. <br /> c - The presence of the analyte may be due to carryover from previous sample injections. <br /> cf - The sample was centrifuged prior to analysis. <br /> d - The sample was diluted. Detection limits were raised and surrogate recoveries may not be meaningful. <br /> dv - Insufficient sample volume was available to achieve normal reporting limits. <br /> f - The sample was laboratory filtered prior to analysis. <br /> fb - The analyte was detected in the method blank. <br /> fc - The analyte is a common laboratory and field contaminant. <br /> hr - The sample and duplicate were reextracted and reanalyzed. RPD results were still outside of control limits. Variability is attributed to sample inhomogeneity. <br /> hs - Headspace was present in the container used for analysis. <br /> ht – The analysis was performed outside the method or client-specified holding time requirement. <br /> ip - Recovery fell outside of control limits due to sample matrix effects. <br /> j - The analyte concentration is reported between the method detection limit and the lowest calibration point. The value reported is an estimate. <br /> J - The internal standard associated with the analyte is out of control limits. The reported concentration is an estimate. <br /> jl - The laboratory control sample(s) percent recovery and/or RPD were out of control limits. The reported concentration should be considered an estimate. js - The surrogate associated with the analyte is out of control limits. The reported concentration should be considered an estimate. <br /> k – The calibration results for the analyte were outside of acceptance criteria, biased high, and the analyte was not detected in the sample. <br /> lc - The presence of the analyte is likely due to laboratory contamination. <br /> L - The reported concentration was generated from a library search. <br /> nm - The analyte was not detected in one or more of the duplicate analyses. Therefore, calculation of the RPD is not applicable. <br /> pc - The sample was received with incorrect preservation or in a container not approved by the method. The value reported should be considered an estimate. ve - The analyte response exceeded the valid instrument calibration range. The value reported is an estimate. <br /> vo - The value reported fell outside the control limits established for this analyte. <br /> x - The sample chromatographic pattern does not resemble the fuel standard used for quantitation.
