In this application note, the Thermo Scientific ISQ 7610 single quadrupole GC-MS system was utilized for the simultaneous analysis of PAHs in water and soil samples, thanks to the extended linear dynamic range of the XLXR detector. For this analysis, a single calibration curve over five orders of magnitude was utilized to analyze water and soil samples, eliminating the need to run separate curves for different matrices therefore increasing sample throughput. The robustness of the system was also demonstrated with extended run of soil and water matrices.
