Routine testing is often performed by GC-MS, allowing labs to improve productivity and decrease cost per sample by consolidating GC-MS screening methods for PAHs and PCBs. Simultaneous analysis of these two contaminant groups often utilizes \u201cXLB-type\u201d columns for separation of PCB 28\/31, but this comes at a cost as some PAH separations tend to suffer. A \u201c5-type\u201d column provides alternate selectivity, making it a suitable phase for method consolidation. The quick GC-MS method for PAHs and PCBs presented here can help labs operate more efficiently, providing excellent chromatography for concurrent analysis of both pollutant classes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This method was developed on an RMX-5Sil MS column because it combines standard \u201c5sil\u201d selectivity with a next-generation TriMax deactivation, creating a highly inert sample flow path. Figure 1 demonstrates that across a fast, &lt;20-minute run, the target PAHs and PCBs exhibited excellent peak shapes and separations. For example, while benz[a]anthracene; chrysene; and PCB 180 normally elute as a triplet, baseline USP resolution (\u22651.5) was achieved on the RMX-5Sil MS column. To assess how consistent column performance was for key parameters, 100 injections at 1 ng on-column were made, and the results were extremely stable with tailing %RSD ranging 3.9-6.6% and retention time %RSD ranging 0.01-0.02%. &nbsp;While this analysis is not a comprehensive view of all PAHs and PCBs of interest, it can be customized for user-specific compound lists\u2014even on different column dimensions\u2014using Restek\u2019s free Pro <em>EZ<\/em>GC chromatogram modeling software.<\/p>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\"
