Semi volatile Organic Compounds (SVOCs) are currently routinely analyzed in multiple environmental matrices by environmental laboratories. SW-846 Method 8270E is the first method published by the Environmental Protection Agency (EPA) allowing the use of Triple Quadrupole GC-MS (GC-MS/MS) for the analysis of semi-volatile organics. The superior selectivity of GC-MS/MS results in better sensitivity than that obtained with traditional Single Quadrupole GC-MS. In addition, when employing GC-MS/MS, a standard autotuning defined by the GC-MS manufacturer is available for spectrum tuning validation, instead of manual tuning using DFTPP. In this study, the performance of Shimadzu’s GCMS-TQ system for the simultaneous analysis of SVOCs included in EPA 8270E was evaluated. All compounds displayed valid calibration curves within a suitable dynamic range for the analysis of these chemicals in environmental samples. Simply performed tuning validation is an additional benefit of using GC-MS/MS. This work demonstrates how GC-MS/MS can enhance workflows for the analysis of SVOCs with EPA 8270E.
