the mix can be used for reporting either PCB con-
gener results or total PCBs. Decachlorobiphenyl and
tetrachloro-m-xylene are appropriate as internal
standard and surrogate standard, respectively. The
PCB congener standard is a very useful addition to
our group of Aroclor® reference mixes.
Figure 2 is a GC/ECD analysis of the 19 PCB con-
geners, with the internal and surrogate standards. To
simplify the work of analysts who monitor both pes-
ticides and PCBs, we used the same 30m, 0.32mm
ID, 0.5µm Rtx®-XLB column and the same condi-
tions in both analyses: the conditions used to obtain
Figure 2 are optimal for very rapid analysis (11.5
min.) of the Method 8082A PCB congeners, as was
true for the pesticides.
If you are performing analyses of organochlorine
pesticides and/or PCBs, an Rtx-XLB® column and
Restek reference materials will save time, help sim-
plify your analysis, improve the quality of your data,
and increase your productivity.
