Advances in Capillary Electrochromatography: Rapid and High-Efficiency Separations of PAHs

Capillary columns packed electrokinetically with 1.5-μm nonporous octadecylsilica particles are used to achieve rapid separations with high efficiencies. A mixture containing five polycyclic aromatic hydrocarbons (PAHs) as test compounds is separated in less than 5 s with 28 kV applied to a column with a packed length of 6.5 cm (10 cm total length). A sample containing 16 PAHs (classified as pr...

Diurnal cycle of PAHs, nitro-PAHs, and oxy-PAHs in a high oxidation capacity marine background atmosphere.

To improve our understanding of the formation and fate of nitro-PAHs, which contribute to the toxicity of ambient particles, the diurnal variation of their ambient concentration was studied concurrently with the corresponding PAH, OH radical, ozone, and oxy-PAH concentration, during an intensive field campaign at an eastern Mediterranean marine background location (Finokalia, Island of Crete) i...

Fullerenes and PAHs in space

Theoretical, observational and laboratory work on the new form of carbon known as fullerenes and its hydrogenated forms (fulleranes) are reviewed. These molecules can be responsible of diffuse interstellar bands, the UV bump, a major feature in the extinction curves measured in many lines of sight in our Galaxy and other galaxies and the anomalous microwave emission detected in several regions ...
