QC Annotations:

1. Please see the attached appendices for a list of data qualifiers and lab identifiers

that may be contained in the report.



# 2. The results have been amended so that 1469-TCDD is correctly identified.

# APPENDIX A: DATA QUALIFIERS / DATA ATTRIBUTES

* The reported concentration exceeds the calibra tion range (upper point of the calibration

curve). 1



# > Indicates high recoveries. Shown with the numeric value at the top of the range. 1



# B The analyte is found in the method blank, at a level that is <=10x the sample

concentration.

C Two or more congeners co-elute. In EDDs C denotes the lowest IUPAC congener in a

co-elution group and additional co-eluters for the group are shown with the number of the

lowest IUPAC co-eluter.

E The reported concentration exceeds the calibra tion range (upper point of the calibration

curve).

EMPC Represents an Estimated Maximum Possible C oncentration. EMPC’s arise in cases where

the signal/noise ratio is not sufficient for peak identification (the determined ionabundance ratio is outside the allowed theoreti cal range), or where there is a co-eluting

interference.

ETH Indicates the presence of a diphenyl ether that a ppears to interfere with the quantitation of

a furan. The reported concentration is the maximum.

H/h If the standard recovery is below the method or SOP specified value “H” is assigned. If

the obtained value is less than half the specified value “h” is assigned. 1



# J Indicates that an analyte has a concentration below the reporting limit (lowest point of the

calibration curve).

ND Indicates a non-detect.

NR Indicates a value that is not reportable.

PR Due to interference, the associa ted congener is poorly resolved.

QI Indicates the presence of a quantitative interference.

Ra The new ratio – [Ra] -- for 2,3,7,8-TCDD following the 37 

# Cl 4 

# -2,3,7,8-TCDD correction is

shown between squared brackets in the DL column. 1



# SI Denotes “Single Ion Mode” and is utilized fo r PCBs where the secondary ion trace has a

significantly elevated noise level due to b ackground PFK. Responses for such peaks are

calculated using an EMPC approach based so lely on the primary ion area(s) and may be

considered estimates. 1



# U The analyte was not detected. The estimated detection limit (EDL) may be reported for

this analyte.

V The labeled standard recovery was found to be outside of the method control limits.

X Indicates results reported from reinjection, refractionation, or repeat analyses.

APPENDIX B: LAB ID IDENTIFIERS

AR Indicates use of the archived portion of the sample extract.

CU Indicates a sample that required additional clean-up prior to MS injection/processing.

D Indicates a dilution of the sample extract. The number that follows the “D” indicates the

dilution factor.

DE Indicates a dilution performed with the addition of ES (extraction standard) solution.

DUP Designation for a duplicate sample.

MS Designation for a matrix spike.

MSD Designation for a matrix spike duplicate.

RJ Indicates a reinjection of the sample extract.

S Indicates a sample split. The number that fo llows the “S” indicates the split factor.
