| Research Abstract |
Atmospheric pressure multiphoton ionization (APMPI) method using a tiny picosecond laser (532 nm, 50 microJ, 500 ps, 1 kHz) was applied for the liquid chromatography and mass spectrometry systems. In contrast to ordinal atmospheric pressure photoionization using VUV lamp and atmospheric pressure chemical ionization methods using Corona discharges, APMPI did not show any background signals originated in eluent and contaminants. A good S/N values were obtained when polycyclic hydrocarbons, one of the atmospheric pollutants, was analyzed by using APMPI.
