On-line liquid distribution chromatographic/spectrofluorometric determination of PAH distribution in coal-derived products
… of polycyclic aromatic hydrocarbons (PAHs) in coal-derived products. The PAHs were isolated by preparative silica gel columns with a hexane mobile phase, and fractionated into five samples based on the number of condensed rings. Each fraction was separated by reverse phase HPLC with an …

Ultra-fine soot investigation in flames
In-flame soot particle size and concentration analysis techniques were developed for high concentrations of ultra-fine soot particles (particle diameters<< 1000 nm) using a Scanning Mobility Particle Sizer (SMPS). The SMPS particle size results were compared to results obtained by thermo phoretic …

Monitoring of atmospheric polycyclic aromatic hydrocarbons through optimization of analytical techniques
… of disease. Polycyclic aromatic hydrocarbons (PAHs) have been widely used as markers of environmental pollutants in the context of ambient air, indoors, as well as in working environments. Sampling, extraction, sample clean up and analysis constitute the principal stages required for the …
