PCB congeners known to be present in Aroclors, known to be present in non-Aroclor mixtures, or present in both. Aroclor congeners are found (>0.20 wt %) in Aroclors 1016, 1221, 1242, 1248, 1254, 1260, or 1262 [40]. Non-Aroclor congeners are found in paint pigments/colorants, adhesives, and sealants [13–16, 18, 19]. For this illustration, we used the coelution scheme produced by the SPB-Octyl capillary column.
