The US Environmental Protection Agency (EPA) developed a method for the analysis of semivolatiles using GC-MS/MS. This method allows the determination of on-column amounts of target compounds to be detected at orders of magnitude lower concentrations than conventional single quadrupole mass spectrometers. New column requirements include enhanced robustness, thermal stability, improved PAH selectivity, and extended lifetime following highly contaminated extracts. This presentation will show specific weaknesses of general-purpose 5-type columns for the analysis of environmental samples and the advantages of this new Rxi-SVOC column when used with tandem mass spectrometers.
