The Cumulative CAMAG Bibliography Service CCBS contains all abstracts of CBS issues beginning with CBS 51. The database is updated after the publication of every other CBS edition. Currently the Cumulative CAMAG Bibliography Service includes more than 11'000 abstracts of publications between 1983 and today. With the online version you can perform your own detailed TLC/HPTLC literature search:

J. Planar Chromatogr. 4, 328-329 (1991). TLC of dihydroxyanthraquinones (1,2-, 1,4-, 1,5-, 1,8, 2,6-) on Kieselguhr G impregnated with paraffin oil and binary mixtures of methanol and water 10:0, 9:1, 8:2, 7:3 and on cellulose with methanol - water 9:1. Detection under UV 254 nm (on Kieselguhr) and by spraying with 0.005% aqueous new fuchsin solution (on cellulose).
J. Planar Chromatogr. 9, 293-296 (1996). TLC of dibenzo-18-crown-6, 4,5(5')-di-tert-butyldibenzo-18-crown-6, dibenzo-16-crown-5, 4,5(5')-di-tert-butyldibenzo-16-crown-5, dibenzo-14-crown-4, 4,5(5')-di-tert-butyldibenzo-14-crown-4, 4,5(5')-di-tert-butyldibenzo-24-crown-8, and dibenzo-24-crown-8 on RP-2, RP-18, or NH2 with methanol - water, isopropanol - hexane, isopropanol - water in different ratios or acetonitrile. The best separations were observed with mobile phases containing 80-90% methanol. Visualization by exposure to iodine vapor and under UV 254 nm. - Separation on RP-18 confirms the order of hydrophobicity of the investigated crown ethers.
J. Planar Chromatogr. 14, 113-118 (2001). HPTLC and TLC of calix[4]arene, 4-tert-butyl-calix[4]arene tribenzoate, 4-tert-butylcalix[5]arene, and pyrene on silica gel and RP-18 W at constant temperature with methanol, ethanol, acetonitrile, and their binary mixtures with water (from 0 to 100%). The best separation of calixarenes was obtained on RP-18 W with acetonitrile - water 9:1. Visualization of pyrene under UV 366 nm and of calixarenes by use of a 20% solution of perchloric acid in water.
CBS 98, 9-11 (2007). Quantitative HPTLC of polycyclic aromatic hydrocarbons (PAH) from water samples, on caffeine-impregnated silica gel, with isopropyl acetate in a precooled (-20 °C, 30 min) twin-trough chamber without chamber saturation over 70 mm at -20°C. After application the dry plate was first equilibrated in the solvent-free trough for 10 min at -20 °C. Qualitative HPTLC at room temperature in the horizontal developing chamber with isopropyl acetate - n-hexane 3:1 over 50 mm. Detection by dipping in paraffin - toluene 1:1 (for fluorescence enhancement). Quantitative determination by fluorescence measurement at UV 366/>400 nm. Qualitative evaluation under UV 366 nm. The method is based on the German standard DIN 38407-7 for quantitative determination of 6 PAH but uses isopropyl acetate as a chlorine-free solvent instead of dichloromethane.
Universal interaction indices for GLC, HPLC and TLC. Chromatographia 20, 283-288 (1965). Proposal of universal interaction indices used in TLC, GLC and HPLC, which can be easily calculated from commonly used retention parameters, such as Rf values, relative retention times etc. Presentation of the calculation examples for polycyclic aromatic hydrocarbons and n-alkanes. Demonstration of the application of the electric interaction indices for studying the retention mechanism.
Chromatographia 25, 643-646 (1988). Investigation of the retention behavior of a group of polycyclic aromatic hydrocarbons having nearly equal ionization potentials but different molecular polarizability values, using reversed-phase TLC on octadecyl-bonded silica with normal alcohols. Discussion of the relationship between retention parameters and molecular polarizabilities of the solutes and solvents.
J. Planar Chromatogr. 4, 497-498 (1991). TLC of 12 PAH’s (anthracene, phenanthracene, pyrene, benz(a)anthracene, benzo(a)pyrene, perylene, chrysene, dibenz(a,h)anthracene, benzo(e)pyrene, triphenylene, coronene) on cellulose acetate with ethanol - toluene - water 17:4:4.
Comparison with the adsorption properties of Florisil. Chromatographia 43, 405-412 (1996). Examination of the retention behavior of positional isomers and polyaromatic hydrocarbons on mixed silica - magnesia layers with various binary eluents. Investigation of the influence of magnesia content in mixed adsorbents and concentration of polar modifier in the eluent on retention. Comparison of the results with those obtained on Florisil using the same eluent by RM correlation. Comparison of chemical character and distribution of active centers on Florisil and mixed adsorbent surfaces by analysis of the structural effects of solutes and the position of points on RM correlation diagrams.
