Surrogate Standards for the Determination of Individual Polychlorinated Biphenyls Using High-Resolution Gas Chromatography with Electron Capture Detection

A method for calibrating an electron capture detector (ECD) for quantitative analysis of all 209 Individual polychlorinated biphenyl (PCB) congeners was developed by using a secondary standard containing 31 surrogate PCB congeners. By use of the relative response factors (RRFs) for 203 of the 209 PCBs determined by high resolution gas chromatography with ECD, RRFs were clustered to allow a commercially available PCB surrogate to represent a group of PCB congeners. With this statistically based approach, the calibration bias was <10% and the range of the percent relative standard deviation for the 31 groups of RRFs was 0–4.9%. © 1985, American Chemical Society.
