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.
J. Chromatogr. 361, 217-221 (1986). TLC of tris- (alkylxanthato) cobalt(III) complexes on silica with 6 solvents (a) benzene, b) toluene, c) cyclohexane, d) carbontetrachloride, e) hexane, f) heptane). Green spots. Rf values increase with increasing carbon number of the alkyl group. There is a linear relationship between the number of carbon atoms in the homologues and the Rm values of the complexes.
J. Chromatogr. 454, 362-366 (1988). TLC of 21 cationic and neutral cobalt(III) complexes on silica with ten solvent systems. Examination of the dependence of Rf values of cobalt(III) complexes on the size of diamine chelate ligands. The method can be used for determining the composition of the corresponding complexes.
Investigation of the separation mechanism for tris(ß-diketonato) complexes of transition metals. J. Planar Chromatogr. 3, 495-499 (1990). Rf values of tris(ß-diketonato) complexes of 20 Cobalt (III), Chromium(III) and Ruthenium(III) have been determined on thin layers of polyacrylonitrile sorbent by the application of two monocomponent and six polycomponent non-aqueous solvent systems, and two aqueous solvent systems. A linear dependence has been established between RM values and the number of 2,4-pentanedionato ligands substituted by 1,3-diphenyl-1,3-propanedionato ligands in tris(ß-diketonato) complexes of the aforementioned metals.
J. Planar Chromatogr. 6, 29-33 (1993). Study of the chromatographic behavior of 36 estradiol and estrone steroids on silica and RP-18 silica with non-aqueous and aqueous - organic mobile phases. Calculation of the slopes of the linear relationship between RM and the volume fractions of the polar organic components of the binary eluents and discussion in relation to the characteristics of the solute eluent, and stationary phase.
J. Chromatogr. 668, 485-494 (1994). Determination of the lipophilicities and specific hydrophobic surface aceas of 16 bioactive heterocyclic compounds by reverse-phase TLC on silica, impregnated with hexane-paraffin oil 95:5, using various eluent systems. Evaluation of the data by using principal component analysis (PCA), separately calculated from the correlation and covariance matrices, and by cluster analysis.
J. Planar Chromatogr. 8, 288 - 291 (1995). Comparison of the efficiency of three different approaches for optimizing separation selectivity in RP liquid-liquid chromatography as exemplified by TLC employing RP-2 stationary phase and methanol-water binary eluents. The three different optimization methods are based on the relationships between retention and binary mobile phase composition proposed by Snyder, Schoenmakers, and Kowalska. The similar optimization power of all three approaches is demonstrated by means of selected examples.
J. Planar Chromatogr. 9, 439-444 (1996). TLC on alumina of eighteen diastereoisomers of type RO2C-CH(Br)-CH(Br)-CO2R was studied with eighteen mobile phases, selected by computer on the basis of Snyder theory, with eluent strength in the range 0.140-0.180 and significantly greater variation in localization, RM, and polarity. The relationship between Rm and log Nb data was in agreement with the Soczewinski equation.
Acta Pharmaceutica Hungarica 68, 49-4 (1998). Molecular investigations can be easily determined both by thin-layer and high performance liquid chromatography. Presentation and discussion of theory and praxis of both methods and the various methods for the calculation of the complex stability.
