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.
J. Chromatogr. 437, 328-332 (1988). Preparative separation of closely related alkaloids from Papaver and Fumaria species on aluminium oxide by centrifugal TLC with cyclohexane - toluene - diethylamine 320:80:1, 160:40:1 or 160:40:3. Flow-rate 0.5-1.5 mL/min. The rotors (1 mm layer thickness) were prepared from a mixture of 40 g basic aluminium oxide, 10g calcium sulfate hemihydrate and 110 mL water.
J. Planar Chromatogr. 2, 53-61 (1989). Construction of the new instrument with the principle of five rotation planar chromatographic methods. The efficiency of the RPC methods demonstrated with the separation of saponin glycosides from Panax ginseng and some furocoumarin isomers from Pastinaca sativa. For preparative separation, an extract from Peucedanum palustre was chosen.
J. Chromatogr. 518, 273-276 (1990). TLC of Chelidonium alkaloids on silica by stepwise gradient with binary and ternary eluents comprising toluene, methanol, ethyl acetate, isopropanol. Detection under UV 366 nm, or by spraying with Dragendorff’s reagent.
J. Planar Chromatogr. 4, 345-359 (1991). Description of the evolution of automated multiple development from manual multiple development through programmed multiple development and discussion of the general role of solvent strength gradients and solvent selectivity emphasizing their application to AMD. The large number of experimental parameters encountered in method development is recognized as one of the main current weaknesses of AMD. The method has, however, a number of attractive features which will ensure continuing interest in the technique.
Anal. Chem. 65, 588-595 (1993). Application of planar chromatography with forced flow development to characterize the kinetic and some thermodynamic properties of octadecylsilanized silica supported by membranes intended for use in solid-phase extraction. Separation of two test mixtures on the membranes with methanol.
Multi-stage development over a constant distance. J. Chromatogr. A 726, 185-192 (1996). Presentation of a theoretical model of multiple development over a constant distance, which is verified with experimental results. Calculation of the final Rf values by computer program for known retention vs. eluent composition relationships for the solutes. Comparison of the predicted and experimental Rf values.
J. Planar Chromatogr. 11, 34-37 (1998). Investigation of silica gel, aluminium oxide, and cellulose plates for their capacity to separate the color pigments of red wine by both adsorption and reversed-phase TLC. RPTLC can be successfully used for the separation of these pigments. - TLC of red wine pigments on silica gel impregnated with paraffin oil with a multistep gradient of water - methanol 3:7 for 3 cm; water - methanol 11:9 for 8 cm; then water - methanol 7:3 for 5 cm. This mobile-phase gradient can, perhaps with slight modification, be used for the same separation in reversed-phase HPLC.
J. AOAC Int. 82, 587-598 (1999). Description of a new automated overpressured-layer chromatographic (OPLC) system which is suitable for analytical and semipreparative separations. The automatic microprocessor-controlled system ensures rapid and reproducible off-line isocratic and stepwise gradient separations. With optimum linear velocity theoretical plate heights of 10 - 30 µm resp. 6 - 15 µm can be reached (on irregular silica gel with an average particle size of 5µm resp 3 µm spherical silica gel). Rapid analytical separations of resveratrol (1555 s) and xanthine by one- (498 s) and two-directional (274 s) off-line developments were accomplished.
