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.
The effect of salts. Chromatographia 21, 312-316, (1986). Determination of the lipophilicity of aniline and 36 ring-substituted aniline derivatives by reversed-phase TLC using NaCl, KCl, MgCl2, AlCl3 and tetramethyl ammonium hydroxide either adsorbed on the silica surface or added to the eluent. Discussion of the effects of salts on chromatographic behaviours. In most cases, the salts decreased the retention power of silica resulting in enhanced mobility of the aniline derivatives. The monovalent cations had the lowest while AlC3 had the highest impact on selectivity due to different ion charges.
Chromatographia 34, 537-539 (1992). Study of the retention behavior and separation ability of reverse- and normal-phase TLC on silica, RP-18 silica and acetylated cellulose with polar and nonpolar mobile phases. Measuring the retentions of a series of amides. Discussion of the retention behavior and separation ability in terms of the nature of the solutes, stationary phases, and eluents.
CBS 93, 2-4 (2004). HPTLC of signaling ceramides on silica gel with a 7 step gradient from methanol over dichloromethane to n-hexane over 42 min. Detection by dipping in manganese chloride reagent for 1 s, followed by drying at 120 °C for 20 min. Quantitative determination by absorbance measurement at 550 nm and Michaelis-Menten regression 2 via peak area. Signaling ceramides are separated from other lipids (shingomyelin, phosphatidylcholine, cholesterol) contained in cellular lipid extracts. Comparison with determination of ceramide formation via isotope labeled standards and conventional TLC method.
Research Journal of Pharmaceutical, Biological and Chemical Sciences 1(4), 152-157 (2010). TLC on silica gel with methanol - 10 mM ammonium acetate 3:2 . The hRf value of ranolazine was 49. Densitometric evaluation at 271 nm. The method was linear in the range of 1-6 µg/band with a mean recovery of 100.0 %.
J. Chromatogr. Sci. 20, 235-237 (1982). TLC of primary aromatic amines (3-methoxy-4-nitroaniline, 2-nitroaniline, 4-methoxy-3-nitroaniline, 3-nitroaniline, 4-chloro-2-nitroaniline, 2-methoxy-3-nitroaniline, 2-methoxy-5-nitroaniline, 2-chloro-4-nitroaniline, 4-chloroaniline, 2-methyl-4-nitroaniline, 4-nitroaniline, 2,4-dinitroaniline on silica with benzene - ethyl acetate 8:2. Detection by exposure to NO2 fumes (HCl + NaNO2) for 10-30 sec., then spraying with N-11-naphthylethylenediamine.
J. Planar Chromatogr. 2, 203-206 (1989). The chromatography of six N-oxides (nicotinic acid N-oxide, metyrapone N-oxide, p-cyano-N, N-dimethyl aniline N-oxide, 3-acetyl pyridine N-oxide, 3-benzylpyridine N-oxide, and pyridine N-oxide) was described for both C-18 and CN-bonded silica gel TLC plates. Using methanol-water solvent systems containing up to 60% methanol the N-oxides had higher Rf values than their respective parent compounds. At concentrations of methanol of 80% or more the order of migration was reversed. Separation of critical pairs was possible by careful selection of one or other of the phases.

Proc. Intern. Symp. on Planar Separations Plan. Chrom. 13-23 (2003). TLC of newly synthesized benzanilides, benzamide and a group of pesticides on RP-18 with aqueous solutions of acetonitrile or methanol with different organic modifier concentrations. Visualization under UV 254 or 366 nm.
