Retention Time References, Quantitation References, Relative Retention Times, and Minimum Levels for CDDs and CDFs

1. The Minimum Level (ML) for each analyte is defined as the level at which the entire analytical system must give a recognizable signal and acceptable calibration point. It is equivalent to the concentration of the lowest calibration standard, assuming that all method-specified sample weights, volumes, and cleanup procedures have been employed.

2. The retention time reference for 1,2 3,7,8,9-HxCDD is <13>C##1,2,3,6,7,8-HxCDD, and 1,2,3,7,8,9-HxCDD is quantified using the averaged responses for <13>C##1,2,3,4,7,8-HxCDD and <13>C## 1,2,3,6,7,8-HxCDD.
