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. 350, 151-168 (1985). TLC on silica with four developing systems: 1) ethyl acetate - methanol - 30% NH3 85:10:5, 2) cyclohexane. - toluene - diethylamine 65:25:10, 3) ethyl acetate - chloroform 5:5, 4) acetone with the plate dipped in KOH solution. Detection by spraying with Dragendorff reagent and acidified iodoplatinate solution. A two-component model accounting for 73% of the total variance. Results of great practical importance in analytical toxicology.
J. Chromatogr. 365, 63-72 (1986). Description of the separation of polar compounds based on the upper section of the "prisma" model for mobile phase optimization. Separation of ginsenosides as an example of application of the model without modifier and of the separation of flavonoid glycosides with a modifier.
J. Planar Chromatogr. 1, 231-234 (1988). TLC on silica and RP-silica having varied pH values with n-hexane, ether, ethyl acetate, toluene, chloroform, THF, benzene, acetone, dioxane, methanol, acetonitrile, methyl butyl ketone for TLC and distilled water for reversed-phase TLC. Detection under UV 366 nm. Discussion of the effect of surface pH value of silica on the retention of dansyl amino acids and the differences between TLC and reversed-phase TLC.
Fres. J. Anal. Chem. 336, 419-422 (1990). TLC of all lanthanoids except Pm in aqueous solutions of five alkali metal chlorides on silica. Visualization by spraying with 0.02% aqueous arsenazo(III) solution and 1 mol/L acetic acid. Examination of the effects of the solvent cations and the solvent anions on the Rf values. Discussion of effects of the salt concentrations on Rf values. For the separation of groups of adjacent lanthanoids typical chromatograms are presented.
J. Chromatogr. 550, 667-675 (1991). Comparison of the log k’ values of 21 natural and synthetic deoxyuridine derivatives from HPLC with the RM values from TLC on alumina with water - 2-propanol 1:9 and 85:15, or dichloroethane - methanol - acetic acid 50:50:0.01. Discussion of the correlation between log k’ and RM values, and the influence of the length of the alkyl chain, of the substituent at position 5 of deoxyuridine on the retention. Influence of the presence of double and triple bounds in the substituent on the retention in different systems.
J. Planar Chromatogr. 12, 51-57 (1999). Analysis of the modern terminology of planar chromatography and suggestion of new variants. Some possible new directions in over-pressured TLC are considered.
Part 3. Evaluation and calibration errors. J. Planar Chromatogr. 18, 256-263 (2005). Third part of a series discussing fundamentals of systematic quantitative errors; systematic errors caused in separation systems; evaluation and calibration errors; nonlinear separation and quantitation techniques; the ,sf4’ procedure for finding summarized systematic errors; systematic errors caused by regulation; conclusions and proposals for quantitative PLC. A correlation function is needed to obtain correct quantitative results from the raw data of a chromatogram - i. e. maximum peak height, peak area of part or or all of a PLC spot, a line or a circle (for circular chromatography): Yi = Ai + Bi x Xi + Ci x (Xi)² + Di x (Xi)³. After 1) Introduction (and example), 2) Evaluation, 3) Calibration errors (3.1 Calibration function found by polynomial interpolation, 3.2 Calibration data analysis, 3.3 Data details for polynomial interpolation, 3.4 Analysis of the ,overall data quality’, the ,data Goodnes’, 3.5 Effect of mathematical accuracy, 3.6 Positioning of the calibration sample ,i’ and the number of different concentrations/amounts to use) follows 4) A possible future of sampling and flexible precise positioning not only of the calibration substances.
