A comparison of PCB/pesticide quantitation using packed vs. Magabore columns
At Argonne National Laboratory (ANL), we are participating in the DOE Environmental Survey Program, which uses Environment Protection Agency (EPA) Contract Laboratory Program (CLP) methods for analysis of environmental samples. For PCB/pesticides, the CLP method requires gas chromatograph/electron capture detector analysis of a primary and secondary column. Currently, samples undergo quantitative analysis on an EPA-required packed column, while confirmation of retention time is on a megabore column. Megabore columns yield higher resolution, which aids in PCB/pesticide identification and improves quantitation. Megabore columns are used in the CLP method for quantitation only after validation of results with the required packed column. To compare the results from both columns, we quantitatively analyzed over 100 water and soil/sediment samples for PCB/pesticides on packed and megabore columns. This study found a wide variance between megabore columns and packed column quantitation, and concluded that no on the type of column was more accurate or precise in PCB/pesticide identification. 4 refs., 6 figs., 7 tabs.
