This Application Note describes a rapid method for analysis of polynuclear aromatic hydrocarbons (PAHs) in soil and sediment samples by GC-MS using an Agilent Low Thermal Mass (LTM) GC/MS system and Capillary Flow Technology QuickSwap for Backflush. The cycle time for GC-MS analysis of PAHs was dramatically improved through the combined use of a narrow-bore (180-µm id) column installed in an LTM module and capillary column back-flushing with QuickSwap. Improvements were achieved while maintaining resolution. Agilent Capillary Flow Technology enabled column backflushing to remove low-volatili- ty material from the capillary column, reducing bakeout and maintenance time. The method resulted in increased sample throughput and lab productivity, while maintain- ing analytical performance.
