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. 320, 281-291 (1985). Reversed-phase TLC of a series of nitroimidazo(2 1-6)thiazoles on silica impregnated with 5 % solution of silicone oil, with glycocoll buffer (0.1M) of pH 13 alone or in various mixtures with acetone or methanol. Determination of RM values. Correlation of extrapolated RM and log k' obtained by HPLC with Hansch values for the derivatives. Discussion of the correlation of their structure with mutagenic activity.

TLC of 8-hydroxyquinoline analogues and 5-nitro-8-hydroxyquinoline on silica with chloroform, chloroform - ethyl acetate 8:2, chloroform - methyl salicylate 9:1, chloroform - amylalcohol 9:1, chloroform - methanol 9:1, benzene - methanol 9:1, ethyl acetate - methanol - acetic acid 15:10:4, ethanol, propanol - water 7:3, NH3 conc. - methanol 1. 5:100, 2. 5:100, 3. 5:100, 4. 5:100, 5. 5:100 and 6. 5:100. Detection under UV 254 nm.
J. Planar Chromatogr. 5, 468-469 (1992). TLC of thioquinanthrene and thioquinanthrene-7-oxide on silica with chloroform - methanol 19:1. Visualization under UV 254 nm. Quantification of the sulfoxide after elution by photometry.
J. AOAC Int. 79, 628-635 (1996). TLC of allantoin in pharmaceuticals on silica with e.g. methanol - acetone - formic acid - water 40:2:1:6 and in urine on cellulose with butanol - acetic acid - water 2:1:1. Detection with pDMAB (Ehrlich's reagent). Quantification by densitometry at 445 nm. TLC as fast and inexpensive semiquantitative method for estimation of allantoin in natural samples.
J. Liq. Chromatogr. Relat. Technol. 29, 2045-2057 (2006). TLC of substituted trans-piperidinones comprising 15 amidolactames and 7 aminolactames on silica gel with 13 mobile phase systems with LSChrom software. The procedure takes into account the adsorption properties of the mobile phase (parameter epsilon), stationary phase, and sample structure expressed by the relevant group.
J. AOAC Int. 93, 1180-1191 (2010). TLC of tropisetron and its acid-induced degradation products on silica gel with methanol - glacial acetic acid 22:3 with chamber saturation for 45 min. Detection under UV light at 254 nm. Quantitative determination by scanning at 285 nm. The hRf values were 44, 84, and 92 for tropisetron and degradates I and II, respectively. Linearity was between 1 and 10 µg/zone. Mean accuracy was 100.2 %. The precision was 0.64 %.The limit of detection and quantification for tropisetron was 0.26 and 0.80 µg/zone, respectively. The intraday and interday precisions were evaluated by assaying freshly prepared samples of tropisetron in triplicate concentrations, i. e. 3, 5, and and 9 µg/zone, resulting in 99.8 %, 100.3 %, and 100.4 %, respectively, for interday precision and 99.7 %, 100.2 %, and 99.7 %, respectively, for intraday precision (with a precision of 0.9 %, 0.6 %, 0.8 % and 0.6 %, 0.4 %, 0.6 %, respectively).
