Gas chromatographic chemiluminescent detection and evaluation of predictive models for identifying nitrated polycyclic aromatic hydrocarbons in a diesel fuel particulate extract
A chemiluminescent detector (CD) has been evaluated for the analysis of nitrated polycyclic aromatic hydrocarbons (nitro-PAH) via gas chromatography. The detector responded linearly to most nitro-PAH from 100 ng to 50 pg using the experimental conditions described in the text. The selective detection of nitro-PAH over other hydrocarbons was compared to the relative selectivities of flame ionization detection and detection with electron impact mass spectrometry and negative ion chemical ionization mass spectrometry. Models have been developed that predict the gas chromatographic behavior of nitro-PAH on SE-52. A gas chromatography/chemiluminescent detector (NO/sub 2/ specific) revealed that a number of nitro compounds were present in a diesel exhaust particulate sample. The models were used to tentatively identify nitro-PAH in the sample. Compound assignment was confirmed by as chromatography/negative ion chemical ionization mass spectrometry and standard addition experiments.
