EXPLANATION OF DATA GUALI FIERS - ORGANIC PARAMETERS
U - This qualifier indicates that the analyte was analyzed
for but not detected.
J - This qualifier indicates that the value is an estimate.
It is used when a compound is determined to be present
based on the mass spectral data but at a concentration
less than the practical quantitati on limit of the
method.
E - This qualifier indicates that a sample result is an
estimate because the concentration exceeded the upper
calibration range of the instrument.
EXPLANATION OF DATA GUALI FIERS - METALS 8 INORGANIC PARAMETERS
U - This qualifier indicates that the analyte was analyzed
for but not detected.
B - This qualifier indicates that the analyte was detected
at a level below the reporting limit but greater than
or equal to the instrument detection limit.
EXPLANATION OF DATA FLACS - ALL PARAMETERS
8 - This flag indicates that an analyte is present in
the method blank as well as in the sample. The client
should consider this when evaluating the data.
E - This flag irdicates the reported value is estimated due
to sample matrix interference.
N - This flag indicates that a post-digestion spike for
GFAA analysis is outside quality control limits.
X - This flag indicates that a surrogate recovery is
outside quality control limits.
Y - This flag indicates a spike or spike duplicate recovery
is outside quality control limits.
Z - This flag indicates a relative percent difference for
a spike and spike duplicate is outside quali Cy
control limits.
* - This flag indicates a relative percent difference for
a duplicate analysis is outside quality control
limits.
- This flag indicates a percent recovery for a standard
is outside quality control limits.
