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.
Herba Hungarica 30, 117-129 (1991). TLC of depside and essential oil components on silica with chloroform – ethyl acetate – formic acid 6:4:4. Detection by spraying with Naturstoff reagent, under UV, or by spraying with 5% methanolic FeCl3. TLC of essential oil components on silica with benzene ethyl acetate 95:5. Visualization by spraying with vanillin – sulfuric acid reagent.

Biochemical Systematics and Ecology 24, 173-174 (1996). TLC of mangiferin and iso-mangiferin on cellulose with ethanol - water 9:17 and dichloromethane - ethanol 1:1 saturated with water.
Chromatographia 59 (1-2), 121-128 (2004). Relationships between Rf values and mobile phase composition have been determined for urea herbicides and fungicides in normal-phase systems (NP) of the type silica-nonpolar or weakly polar diluent (heptane, toluene, diisopropyl ether) – polar modifier (ethyl acetate, tetrahydrofuran, dioxane, ethyl-methyl ketone and 2-propanol). These relationships constitute a retention database which has enabled to choose optimum systems for preliminary fractionation of a multicomponent mixture of pesticides by zonal micropreparative TLC. The mixture was applied from the edge of the layer in the “frontal + elution” mode which increased the separation efficiency because of displacement effects. The separated simpler fractions were applied to a silica plate and rechromatographed. The plate was videoscanned, furnishing a real picture of the plate showing preliminary separation of the simpler pesticide fractions. Complete separation of the fractions was carried out by two-dimensional thin-layer chromatography on plates with chemically bonded-cyanopropyl silica stationary phase using non-aqueous eluent in the first direction and aqueous reversed-phase eluent in the second direction.
J. Sep. Sci. 30, 964-970 (2007). Multidimensional planar chromatography of a mixture of five groups of pesticides: (1) diuron, isoproturon, and lenacil; (2) monolinuron, propoksur, carbaryl, and simazine; (3) alachlor and dinoseb; (4) trifluralin, tetradifon, p,p´-DDT, and 4,4´-dibromobenzophenone; (5) hexachlorobenzene. The silica gel plate was developed in the first dimension with ethyl acetate – n-heptane 1:3, and then turned by 90°. Portions of the stationary phase were sequentially removed to ensure that the mobile phase of the following developments reaches only the target spots: (2) chloroform – n-heptane 19:1 (4) acetone – n-heptane 1:59, (3) toluene, and (1) ethyl acetate – dichloromethane 1:9. The plate was dried between 5 and 15 min before each development. Detection under UV light at 254nm.
J. Planar Chromatogr. 21, 197-198 (2008). TLC of endosulfan on silica gel with n-hexane - acetone 4:1 in a saturated twin-trough chamber. Detection by spraying with 5 % aqueous sodium hydroxide solution followed by heating for 5 min. The air-cooled plate was then sprayed with a 2 % solution of m-dinitrobenzene in dimethyl sulfoxide. The limit of detection was 5 µg.
