High-energy collisional spectroscopy in qualitative and quantitative analysis of diesel particulates.
High-energy collisional spectroscopy provides a powerful analytical method for the characterization of polynuclear aromatic hydrocarbons present in diesel particulates. The absence of any need for extraction procedures and the large amount of information available from collisional spectra makes this technique of great interest. In particular, 3-methylcholanthrene can be determined from the daughter spectra of its molecular ion, with methylene iodide as internal standard.
