J. Liquid Chromatogr. 8, 1207-1224 (1985). Investigation of the effect of modifier concentration - methanol, isopropanol, acetonitrile, dioxane - on the retention of 37 aromatic compounds with various substituents for systems of the RP-2-type (silanized silica) - water - organic modifier. Discussion of the correlations between the retention behaviour of the four modifiers.

J. Chromatogr. 552, 613-623 (1991). Demonstration of the advantages of storage of the effluent from a reverse-phase column LC separation on a TLC plate for the separation and identification of polycyclic aromatic hydrocarbons in a marine sediment sample. Deposition of the effluent from a microbore LC column on a linearly moving TLC plate through a spray jet assembly interface. Identification of 11 polycyclic aromatic hydrocarbons by measuring their fluorescence excitation and emission spectra on the TLC plate with a conventional spectrometer.

J. Planar Chromatogr. 9, 203-207 (1996). TLC and OPLC of hydroxy derivatives of polycyclic aromatic hydrocarbons (1-naphthol, 2-naphthol, 2,3-dihydroxynaphthalene, 2,7-dihydroxynaphthalene, 1,3-dihydroxynaphthalene, 1,5-dihydroxy-naphthalene, 9-hydroxyphenanthrene, 1-hydroxypyrene) on RP-18 with acetonitrile - water 1:1 or 3:2 and methanol - water 3:1 for planar chromatography and acetonitrile - water 3:2 for OPLC. Visualization under UV 254 and 365 nm; the plates were then sprayed with fast blue B salt solution and observed again under UV 365 nm.

J. Planar Chromatogr. 14, 80-87 (2001). HPTLC of 45 aromatic hydrocarbons (phenols, aromatic compounds with proton-acceptor groups, aromatic compounds with proton-donor and proton-acceptor groups) on RP-18, RP-18 W, and silanized silica gel with mobile phases containing appropriate proportions of water and organic solvent (methanol, acetonitrile or tetrahydrofuran) and 1% acetic acid. Visualization under UV. The selectivity of the RP-TLC systems tested is highly dependent on the mobile-phase modifier used.

Analytical Methods 2, 521-531 (2010). An HPTLC method for determination for paliperidone in formulation as well as for in vitro release studies has been developed. HPTLC on silica gel with methanol - ethyl acetate 4:1. The hRf value was 54. Quantification was performed by densitometric evaluation at 254 nm. The method was linear in the range of 100-600 ng/band. The method was suitable for estimation of the drug in mucoadhesive microemulsion formulations, as well as for solubility and diffusion studies.
