Abstract
Recent advances in column and instrument technology have made the development of a new generation of high-resolution microcolumn liquid chromatography possible. In addition to offering reduced solvent consumption, this chromatographic technique also yields higher mass sensitivities than those in conventional systems. The applicability of this technique to the analysis of polycyclic aromatic hydrocarbons (PAH) was investigated. PAH in the extract from diesel particulate matter were analyzed to demonstrate the utility of this approach combined with the computer-assisted retention prediction. The technique made clean and high cost-performance environmental analysis possible.
