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. of Natural Products 52, 337-341 (1989). TLC on silica with diethyl ether - hexane 4:1. Visualization with anisaldehyde/sulfuric acid reagent.
Arzneim.-Forsch. 39, 831-832 (1989). TLC of the acid hydrolysis product of bromfenac on silica with chloroform – acetone 8:2 and detection by spraying with Bratton-Marshall reagent (for differentiation between bromazepam, 3-hydrobromazepam and bromfenac).
J. Planar Chromatogr. 3, 271-272 (1990). TLC of mercury-metal mixtures (as cations) on stannic silicate as ion-exchange layer with 1 M NH4Br. Detection after drying by spraying with copper solution (5 % CuSO4 · 5 H2O) and, after drying again, with a solution containing 5 g KI and 10 g Na2SO3 in 100 mL water. Quantification by densitometry (absorbance at 500 nm).
J. AOAC Int. 76, 1394-1395 (1993). TLC of ethyl parathion, methyl parathion, and fenitrothion and metabolites (extracted from visceral tissue) on silica with hexane - acetone 9:1. Detection by spraying with 5% stannous chloride solution, heating for 10 min. at 100 °C, after cooling spraying with freshly prepared 5% sodium nitrite solution in 10% acetic acid, followed by 1-naphthylamine reagent resulting in dark pink-orange spots. Detection limit of p-nitrophenol (a metabolite of the parathions) about 1 µg.
J. Planar Chromatogr. 8, 143-144 (1995). HPTLC of diazepam, nitrazepam, oxazepam, methaqualone, heroin, on silica with hexane - methanol - acetone 15:3:2, benzene - acetone - ethanol 8:1:1, and chloroform - acetone 8:2. Detection by inspection under UV 254 nm and spraying with Dragendorff's reagent. Quantification by comparison against standards.
J. Planar Chromatogr. 9, 217-220 (1996). TLC of the degradation products of ethylenebisdithiocarbamate (i. a. ethylenethiourea, ethyleneurea, urea, and ethylenediamine on silica with acetone, acetone - water 99:1, 95:5, 90:10, and ethanol. Visualization reagents were sodium nitroferricyanide solution, iodine vapor and Ehrlich's reagent.
CBS 91, 5-7 (2003). HPTLC-AMD of benzodiazepines from serum on lichrospher silica gel with a 9-step gradient based on methanol and diisopropyl ether over 80 mm. Densitometric evaluation by absorbance measurement at 230 and 320 nm followed by spectra recording from 200 to 330 nm.

TLC of the active components of „ecstasy“ (MDMA, PMA, PMMA, and ephedrine) on silica gel with 10 mobile phases. The simplex method has been employed to find the optimum composition of the eluent chloroform - dioxane - methanol - ammonia - acetonitrile 7:30:4:3:30. Detection under UV light at 254 nm.
