摘要：

The laser breakdown time-of-flight mass spectrometry was developed and applied to detect the breakdown patterns of hydrocarbons that are significant to improve the detectability of heavy metals compounded in various mixtures such as particles and hydrocarbons. The laser wavelength dependence of this method was evaluated using 1064, 532, and 266nm laser outputs. Breakdown processes using 1064 and 532nm outputs showed less interference of fragmentation for the detection of various heavy metals. The method was applied to various hydrocarbons and it showed the possibility of categorization of hydrocarbon groups using the pattern of breakdown products.
