Cumulative CAMAG Bibliography Service CCBS
Our CCBS database includes more than 11,000 abstracts of publications. Perform your own detailed search of TLC/HPTLC literature and find relevant information.
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:
- Full text search: Enter a keyword, e.g. an author's name, a substance, a technique, a reagent or a term and see all related publications
- Browse and search by CBS classification: Select one of the 38 CBS classification categories where you want to search by a keyword
- Keyword register: select an initial character and browse associated keywords
- Search by CBS edition: Select a CBS edition and find all related publications
Registered users can create a tailor made PDF of selected articles throughout CCBS search – simply use the cart icon on the right hand of each abstract to create your individual selection of abstracts. The saved items can be printed to PDF using the print function of your web browser.
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 31 over 50 mm. Detection by dipping in paraffin - toluene 11 (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 1744.
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.
J. Planar Chromatogr. 14, 208-210 (2001). Separation of dyes, polycyclic hydrocarbons (phenanthrene, benzopyrene, anthracene, fluoranthene, pyrene, triphenylene, azulene, naphthacene, chrysene, perylene) and a vegetable chlorophyll extract on plates prepared from Piresorb A, silica gel, luminophore and liquid glass as binder with benzene, hexane, benzene - hexane 14 and ethyl acetate - acetonitrile 37. For flow TLC it is necessary to use TLC plates with sorbents different from those used in classical TLC.
J. Planar Chromatogr. 20, 221-26 (2007). TLC of seven azaarenes, acridine, benzo(h)quinoline, benzo(a)acridine, benzo(c)acridine, dibenzo(a,c)acridine, dibenzo(a,j)acridine, and dibenzo(a,h)acridine, on RP-18 in a horizontal chamber with dichloromethane - n-hexane - 2-propanol 60401. After drying visualization under UV light at 254 and 366 nm. Quantification by densitometric fluorescence measurement at 380 nm. Limits of determination were from 0.04 to 0.30 ng/zone.
J. Chromatogr. 303, 190-192 (1984). Study of the masking effects of silica, impregnated with amino acids, nucleic acid bases, and organic acceptors, on "charge-transfer" TLC behaviour of pyrene. Discussion of the interaction between the impregnant and pyrene, between silica and pyrene and between silica and impregnant.
