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. The saved items can be printed to PDF using the print function of your web browser.
J. Planar Chromatogr. 20, 483-486 (2007). New method for determination of log P for selected tocopherols, which makes use of Rf, topological indices, and log P according to Rekker. HPTLC of alpha-, beta-, gamma-, and delta-tocopherols on RP-18 with ethanol or ethanol - water 191. Detection by spraying with a mixture of equal volumes of solutions of dipyridyl in methanol (0.5%) and iron(III) chloride in methanol (0.2%).
J. Sep. Sci. 36, 2703-2708 (2013). HPTLC of biotin in Euphausia superba on silica gel with dichloromethane - 2-propanol - methanol 332 + 1 drop glacial acetic acid. Detection (1) by spraying with 0.1 - 1 % 4-(dimethylamino)cinnamaldehyde and sulfuric acid in ethanol, followed by drying for 5 min and spraying with liquid paraffin - chloroform 110. Alternatively, biotin was detected (2) by spraying with 0.05 % potassium permanganate. Quantitative determination by absorbance measurement at 530 nm for (1) and 400 nm for (2). The hRf value of biotin was 50. Linearity was in the range of 340-3310 ng/zone for both (1) and (2). LOD and LOQ were 50 and 90 ng/zone for (1) and 60 and 100 ng/zone for (2). Average recoveries were 99.6 % for (1) and 99.7 % for (2). Intermediate intra- and inter-day precision was below 2 % (n=3).

J. Planar Chromatogr. 3, 149-152 (1990). HPTLC of vitamin B1 on silica with methanol - NH3 (25%) - acetic acid - chloroform 18211. Postchromatographic derivatization with tert-butyl hypochlorite or potassium hexacyanoferrate(III) - sodium hydroxide. After fluorescence enhancement by dipping the plates into a mixture of chloroform - liquid paraffin - triethanolamine 611. Quantification by in situ fluorometry. Detection limit 500 pg vitamin B1 per chromatogram zone.

J. Liq. Chromatogr. & Relat. Technol. 29, 2159-2165 (2006). HPTLC of beta-carotene and lutein on RP-18 (prewashed with dichloromethane - methanol 11) with petroleum ether (35-55°C) - acetonitrile - methanol 112 in a twin-trough chamber with chamber saturation for 15 min. Evaluation under white light. Experiments were done rapidly in subdued light to prevent pigment degradation. Quantification by densitometry at 448 nm for lutein and 455 nm for beta-carotene.
