Analysis of multiple matrices with a single calibration curve for polycyclic aromatic hydrocarbons (PAHs) with the ISQ 7610 GC-MS system following EPA Method 8270E

In this application note, Thermo Fisher Scientific demonstrates the capability of the Thermo Scientific™ ISQ™ 7610 single quadrupole mass spectrometer, equipped with the XLXR™ detector, for analyzing 19 polycyclic aromatic hydrocarbons (PAHs) in soil and water according to EPA Method 8270E. PAHs are pervasive environmental contaminants with toxic effects, necessitating strict monitoring. The note addresses challenges faced by analytical laboratories, such as chromatographic resolution, linearity, and maintenance requirements.
