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. You can export your saved items to PDF by clicking the download icon.
Chinese Anal. Chem. (Fenxi Huaxue) 19, 1085-1088 (1991). Investigation of a method for rapid selection of the optimal solvent combination in TLC, by using a plot of Rf values against solvent polarity. Some examples.
Chromatographia 36, 330-336 (1993). Presentation of equations for the final Rf values for mobile phase gradient multiple development. Computer simulations of gradient development for both modes of TLC for the preliminary optimization of gradient programs.
J. Planar Chromatogr. 10, 411-415 (1997). Description of a simple method developed for optimization of multicomponent mobile phases. The method is based on seven isocratic experiments with binary, ternary, and quaternary mobile phases. hRf values were used as simple optimization criteria. Quaternary mobile phases usually contained weakly polar solvents as the so-called 'strength moderator'. The influences on the chromatographic separation of mobile phase strength and of the kind of moderator were demonstrated.
Chromatographia 61 (5-6), 307-309 (2005). Similarities and differences between the retention characteristics of octadecyl silica gel wettable with water used in TLC and RP-18 used in HPLC have been elucidated by use of the linear relationships between log k and RM. The stationary phases compared were investigated with the same mobile phases - binary mixtures of methanol and water, acetonitrile and water, and tetrahydrofuran and water. For these adsorbents of the same type but differing in specific surface area the correlation line was shifted by log (alpha system I / alpha system II). High values of the correlation coefficients obtained over the whole range of mobile phase organic modifier concentration examined indicated that the TLC systems could be used to predict HPLC conditions for flavonoid separation.
J. Chromatogr. 520, 402-410 (1990). Study of the reverse phase TLC retention of some organic electrolytes on RP-18 silica. Optimization of the retention and selectivity for some N-phenylamides of benzoylacetic acid by changing the content of the organic modifier methanol. Comparison with ion-pair reverse phase HPLC.
J. Chromatogr. 556, 81-84 (1991). Presentation of a survey of published optimization procedures in TLC. In one-dimensional TLC, selection of mobile phase through either computerized or non-computerized methods such as simplex, overlapping resolution map. Proposal of resolution-based criteria and others such as principal component analysis, etc. In two-dimensional TLC, the aim is to find two systems exhibiting the least correlation.
Anal. Letters 27, 1031-1054 (1994). The method is reported to be capable of finding the best system and the optimal combination of two or more TLC systems according to the partition coefficients.
J. Planar Chromatogr. 10, 358-361 (1997). TLC of seven PAHs (7-, 8-hydroxy-, trans-7,8-, trans-9,10-dihydroxybenzo(a)pyrene, benzo(a)pyrene, 1,2,5,6-dibenzanthracene, chrysene) on cellulose acetate with various solvent systems and application of principal-components analysis (PCA) to the experimental results in order to find the optimum solvent system for the separation of the hydrocarbons of interest.
