The project developed tandem mass-spectrometric techniques for the analysis of the polar fractions from the soluble organic fractions of NBS SRM No.1650 diesel-exhaust particulates. Three subfractions, numbered Fractions 7 through 9, were used for the development. Instrumentation utilized was a Kratos MS-50 triple analyzer, which consists of a high-resolution MS-I, a standard Kratos MS-50, and a low resolution MS-II, an electrostatic analyzer. Two modes of spectrometer scanning, acquisition of daughter-ion spectra, and constant neutral loss (CNL) were explored. Two methods of sample ionization, Fast atom bombardment (FAB), and electron ionization (EI) were investigated. Negative-ion chemical ionization (NICI) was subsequently investigated to improve specificity and sensitivity. The MS/MS spectra of 12 nitro-PAH standards were determined and a detection limit of 1 picogram of material was established.
