Gas chromatography resonance-enhanced multiphoton ionization time-of-flight mass spectrometry (GC/REMPI-TOFMS) using a nanosecond laser has been applied to analyze the 16 polycyclic aromatic hydrocarbons (PAHs). The excited-state lifetime, absorption characters, energy of electronic states of the 16 PAHs were investigated to optimize the ionization yield. The results suggested that REMPI is superior to elctron impact ionization method for soft ionization, and suppresses the background signal caused by the aliphatic hydrocarbons. Thus, GC/REMPI-TOFMS is a more reliable method for the determination of PAHs present in the environment.
