J. High Resol. Chromatogr. 8, 265-266 (1985). Description of gravity flow circular TLC for preparative separations by which the polycyclic aromatic hydrocarbon fraction of a creosote extract is isolated. A 200 Ál concentrated extract spotted at the center of the plate positioned 1 cm beneath the stem of a separation funnel. The spot was eluted with hexane, and the PAH-band focused with benzene. Detection under UV light.Polycyclic aromatic hydrocarbons, preparative TLC.

J. Planar Chromatogr. 10, 38-43 (1997). Under TLC conditions a mixture of C60 and C70 fullerenes can be separated on NH2, RP-18 and diol plates and on neutral and basic alumina by use of such eluents as hexane and i-octane and their mixtures with xylene or 1,2-dichlorobenzene. Chamber saturation has a negative influence on the separation. The separation of C60 and C70 fullerenes on silica, however, is achieved by developing the plate with hexane containing 5% pyridine (or iso-octane - pyridine 95:5) in a saturated chamber. The quantity of substance in the starting spot should not exceed 0.4 - 0.5 µg. Detection by densitometry at 254 and 366 nm.

Proc. Intern. Symp. on Planar Separations, Planar Chromatography 2001, pp. 301-308. HPTLC of benzo(a)pyrene, pyrene, fluoranthene, anthracene, fluorene and hair extracts on silica gel with hexane - dichloromethane - nitrobenzene (5:5:x, where x changed from 0.01 ml up to 0.5 ml); best results with a nitrobenzene content of 0.1. Quantitation by densitometry at 365 nm. The concentration of PAHs in human hair was in the range of 0.005-0.2 µg/g hair.

J. Planar Chromatogr. 22, 255-263 (2009). TLC of 25 triphenylmethane derivatives using paraffin oil-coated silica gel and acetone-water mixtures, in which the acetone content varied between 40 and 70 % in increments of 10 %. Dual retention behavior is observed for triphenylmethane derivatives in reversed phase HPTLC when the composition of acetone-water mobile phase is varied. The physicochemical and molecular properties of triphenylmethane derivatives lead to an unusual retention behavior, which was investigatd by traditional quantitative structure-retention relationship modeling and by 3D molecular modeling. Lipophilicity was found to be the most important molecular property governing the retention of triphenylmethane derivatives.
