Organic Data Qualifiers <br /> A -- This qualifier indicates that a TIC is a suspected aldol-condensation product <br /> B -- This flag is used when the analyte is found in the associated blank as well as the <br /> sample This notation indicates possible blank contamination and suggests that the <br /> data user evaluate these compounds and their amounts carrefully <br /> C -- The "C" flag indicates the presence of this compound has been confirmed by the <br />' GC/MS analysis <br /> D This qualifier is used for all the compounds identified in an analysis at a secondary <br />' dilution factor "D" qualifiers are used only for the samples reported at more than one <br /> dilution factor <br /> E -- This flag indicates that the value reported exceeds the linear calibration range for that <br /> compound Therefore, the sample should be reanalyzed at the appropriate dilution <br /> The "E" qualified amount is an estimated concentration, and the results of the dilution <br />' will be reported on a separate Form I <br /> I -- The qualifier indicates that the reporting limit to the "I" qualifier has been raised It <br /> is used when the chromatographic interference prohibits detection of a compound at a <br /> level below the concentration expressed on the Form I <br /> J -- Indicates an estimated value It is used when the data indicates the presence of a <br /> target compound below the reporting limit or the presence of a Tentatively Identified <br /> Compound (TIC) <br /> N This qualifier indicates presumptive evidence of a compound This flag is only used <br /> for Tentatively Identified Compounds (TIC), where the identification is based on a <br /> mass spectral library research It is applied to all TIC results For generic <br /> characterization of a TIC, such as chlorinated hydrocarbon, the "N" qualifier is not <br /> used <br /> P -- This qualifier is used for target analytes when there is a greater than 40% difference <br /> for detected concentrations between the two columns or detectors The concentration <br /> value is reported on Form I and flagged with a"P" <br /> U -- Indicates the compound was analyzed for but not detected The number adjacent to <br /> the "U" qualifier indicates the reporting limit for that compound. The reporting limit <br /> can vary from sample to sample depending on dilution factors or percent moisture <br /> adjustments when indicated <br /> 00C4 <br />
