  6. Data Qualifier Definitions


    J
    Value is an estimated amount due to noncompliance with established or project-specified criteria in any or all of the following categories:
      • exceedance of holding times
      • outside established range of calibration linearities
      • continuing calibration check exceedance
      • IS area deviation
      • analytical replicate variability
      • exceedance of GFAA QC (MSA correlation coefficient deviation)
      • ICP-AES serial dilution performance
      • surrogate and MS/MSD (parameter) recoveries
      • LCS performance
      • multi-component parameter constituents' variabilities
      • reference material performance
    N
    Result is based on presumptive evidence generally due to mass spectral matches outside criteria (consequent to low purity matches; coeluting chemical interferences). Associated value is considered an estimate.
    U
    Substance not detected at the associated value. Associated value is a quantitation limit due to any of the following circumstances:
      • equivalent level limited by instrument detection limit
      • lowest limit of established calibration
      • lowest limit established by potential bias contributed by blank levels - lowest level distinguishable from analytical background
      • presence of chemical interferences precludes positive identification of analyte at associated value
    M
    Concentration is a mean value of either laboratory replicates (e.g., grain size data) and/or field duplicates and splits.
