| Abstract: | The "soft"ionization mass spectra of anthracene, chrysene , dibenz [a, h] anthracene and coronene have been studied using pulsed laser desorption/ionization time-of-flight mass spectrometry. The analying results of anthracene,chrysene,dibenz[a,h]anthracene and coronene mixture show that laser desorption/ionization time-of-flight mass spectrometry is one of sensitive methods'for PAH detection. For coronene, the detection limit is l10-15mol. |
