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.
Chromatogr. 2, 287-289 (1985).(Chinese) (Application of the chord distance method to the selection of thin-layer chromatography and paper chromatography optimal combination.) Study on the cluster analysis by using weighted pair-group and shortest distance methods for TLC of 26 food dyes with 10 developing systems. Method optimization. The same study was made for paper chromatography of 14 amino acids with 5 developing system. The results showed advantages of the method.
Reinvestigation of the effects of solvent pH on Rf values. J. Chromatogr. 354, 99-106 (1986). Ion-pair reversed-phase TLC of 4 organic acids on silica, paraffin-impregnated silica, and on C 18-bonded silica with 4 ion-pair- reagents. Investigation of the effects of solvent pH on Rf values. Discussion of some possible explanation and the potential usefulness of the phenomenon. Rf values of the compounds were unaffected by solvent pH, when tetra-n-butylammonium iodide and tetra-heptylammonium bromide were used as ion-pair reagents, but significant dependence of Rf on the solvent pH was found when cetrimide and cetyltrimethylammonium bromide were used.
Chromatographia 25, 82-86 (1988). Determination of the lipophilicity of 33 nitrostyrene derivatives by reversed-phase TLC on three alkyl- bonded silicas with methanol. Discussion of the relationship between RM value of each compound and the concentration of the organic solvent, the retention strength and selec tivities of the three bonded phases, and the impact of the change of methanol concentration on the retention.
J. Chromatogr. Sci., 26, 325-330 (1988). Investigation of the chromatographic behavior of inorganic ions on Sephadex G-25 with acetone - water mixed eluent system in TLC and CC. Emphasis on the effects of eluent electrolyte and of the solvent compositions inside and outside the gel beads. Evaluation of the partition effect on the retention mechanism for different salts. Proposal of a theoretical model interpreting the effect of the background eluent ions on the capacity factors of the analyte ions.
Thin-layer chromatographic retentions on silica of some (E)- and (Z)-oxazolones and related cinnamates as a function of mobile phase effects or Hammett constants. J. Chromatogr. 545, 161-175 (1991). Study of the TLC behavior of 20 diastereoisomeric 1,1-disubstituted 2-arylethenes [(Z)- and (E)-oxazolones and - cinnamates] on silica with 40 mobile phases. Correlation and discussion of the relative retentions and the retentions themselves with solvent selectivity effects of Hammett constants of the various substituents on the aryl group.
2. Experimental condition affecting resolution and Rf value.) (Japanese). Kagaku to Kyoiku (Jap. J. Sci. & Educ.) 43 (3), 178-181 (1995). Demonstration of the effect of the experimental conditions, such as pre-saturation, developing distance, developing solvent system, and the stationary phase, on the degree of resolution and Rf value in TLC analysis.
CBS 81, 2-5 (1998). The performance and reliability of result of both procedures is comparable - HPTLC being slightly better than HPLC. For the assay of phospholipids in pure substances, pharmaceutical products and lecithin HPTLC is more cost efficient than HPLC by a factor of 2.5.
An in vivo study. Polish Journal of Pharmacology and Pharmacy 39, 379-386 (1987). TLC of imipramine, desipramine and their 2-hydroxy homologues on silica with chloroform - isopropanol 10:1, intermediate drying and isopropanol - chloroform - water - 25 % NH3 50:30:20:2; localizing spots under 254 nm UV after spraying with water; quantification by spectrophotometry after elution. Determination limit 0.5 µg/sample.
