" <br /> DSL-1 Although sample contains compounds in the retention time range associated with diesel,the chromatogram was not consistent <br /> with th3 expected chromatographic pattern or"fingerprint". However,the reported concentration is based on diesel: <br /> GAS-1 Although sample contains compounds in the retention time range associated with gasoline,the chromatogram was not consistent <br /> with the expected chromatographic pattern or"fingerprint". However,the reported concentration is based on gasoline. <br /> QM-02 The RPD and/or percent recovery for this QC spike sample cannot be accurately calculated due to the high concentration of <br /> analyte inherent in the sample. <br /> QM-8 MS/MSD recovery data could not be generated due to insufficient sample. LCS/LCSD data validate methodology. <br /> QR-02 The RPD result exceeded the QC control Iimits;however,both percent recoveries were acceptable.Sample results for the QC <br /> batch were accepted based on percent recaveries and completeness of QC data. <br /> R-02 Elevated Reporting Limits due to limited sample volume. <br /> DET Analyte DETECTED <br /> ND Analyte NOT DETECTED at or above the reporting limit <br /> NR Not Reported <br /> dry Sample results reported on a dry weight basis <br /> RPD Relative Percent Difference <br />
