Over the years, Restek has run applications on a long list of columns for this analysis. It does require a primary and secondary column for analysis, since there is not one column that perfectly separates all compounds on the list simultaneously. Keep in mind that EPA Method 8330B <\/a>allows for alternate columns versus the ones listed if you can demonstrate proficiency by presenting valid data that meets QC acceptance criteria as described in Method 8000<\/a>. Our Innovations chemists have worked hard to make column selection easier for this and get you started in the right direction for optimization.<\/p>\n\n\n\n

So far, we have determined optimal conditions for two pairs of columns that we recommend above all other combinations. For traditional HPLC systems with a 400 Bar pressure limit, we suggest using an Ultra C8 as the primary column and an Ultra Aromax as the secondary (confirmatory) column.<\/p>\n\n\n\n

Here are chromatograms. <\/p>\n\n\n
