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) 23, 1182 (1995). Presentation of an equation for correlating the TLC retention values and carbon numbers under defined conditions.
J. Chromatogr. A 788, 207-211 (1997). Prediction of Rf in a mobile phase which is a binary mixture of a strong and weak solvent by using either a second order or a third order polynomial equation, based on the mole fraction of the strong solvent as the independent variable and p-nitrobenzyl esters of 15 dansyl amino acids as model solutes for TLC on silica gel with each of 5 different mobile phases. Discussion of the accuracy of the prediction.
J. Planar Chromatogr. 12, 301-305 (1999). HPTLC of 25 2-cyano-3-methylthio-3-substituted amine acrylates on RP 18 with methanol - water mixtures (from 65 to 90% in 5% steps). Detection under UV. It was shown that the retention data of a compound can be predicted from structural parameters; it is thus possible to predict the retention of a compound without synthesizing it which is of particular interest in molecular design investigations.
Proc. Intern. Symp. on Planar Separations Plan. Chrom. 369-375 (2003). TLC of betaxolol HCl, propanolol HCl, celiprolol HCl, oxprenolol, karvedilol, metoprolol tartrate, and atenolol on RP-18 with water - acetonitrile and water - dioxane in different concentrations. Visualization under UV 254 nm.
Chromatographia 58 (11-12), 781-788 (2003). Ten urea herbicides and fungicides have been separated by use of two-dimensional thin-layer chromatography. The largest differences are obtained by combination of normal-phase (NP) system and reversed-phase (RP) system on cyanopropyl-bonded polar adsorbents and on two-adsorbent layer containing a narrow zone of octadecyl silica and adjacent a wide zone of silica (or vice versa). The greatest spread of points was obtained for combination of nonaqueous NP systems with ethyl acetate on silica and RP systems comprising a polar solvent (methanol) in water on octadecyl silica adsorbent wettable with water (RP-18W). A good spread of points was also obtained for pairs of normal-phase systems with heptane-ethyl acetate mobile phases and reversed-phase systems with water-dioxane mobile phases, both on cyanopropyl-bonded polar adsorbents. The correlations of Rf values in NP/RP systems were utilized in practical separation of a mixture of ten urea pesticides using 2D-TLC on these adsorbents. The plates were scanned and videoscanned showing the real pictures of TLC chromatograms.
J. Chromatogr. Sci. 46 (10), 907-911 (2008). Examination of M(DEDTC)2 (M = Cu, Co, or Ni) and M(PyDTC)2 (M = Cu or Co) complexes prepared by reactions of sodium diethyldithiocarbamate (NaDEDTC) and ammonium pyrrolidinedithiocarbamate (NH4PyDTC) with metal (II) nitrates. Qualitative analysis and separation using TLC systems in the literature. Reexamination and discussion of the already known separation behaviour of the mentioned metal cations and their complexes in the context of relation to the crystal field theory (CFT) and TLC. Based on the chromatographic data it was found that CFT is closely related to the TLC separation of these metal cations and their complexes. This study is useful in understanding the linkage between the CFT of coordination chemistry and the chromatographic parameters, e.g., hRf value and theoretical plate numbers of the complexes.
J. Planar Chromatogr. 25, 184-189 (2012). The author reviewed the effects of the localization of molecules of solute or solvent on the adsorbent surface in adsorption chromatography, particularly on sample retention and resolution.
