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. Planar Chromatogr. 7, 22-24 (1994). TLC of surfactants (anionic, cationic, non-ionic, amphoteric) by four-fold development on silica with 1. methanol - 2 N NH3 3:1, 2. THF - acetone 1:9, 3. chloroform - methanol 9:1, 4. chloroform - methanol - 0.1 N sulfuric acid 80:19:1. Visualization by dipping in Dragendorff's reagent. The reliability of the method has been tested for 16 surfactants, for which the Rfs are reported.
J. Planar Chromatogr. 23, 250-254 (2010). TLC of 30 food additives (aldehydes, organic acids, esters and alcohols, and various sodium salts) on titanium(IV)silicate ion-exchanger with 10 different mobile phases: e. g. methanol, heptane - diethylether 4:1, aqueous ammonia - methanol - ethyl acetate 1:3:6, methanol - aqueous ammonia 9:1, methanol - ethanol 17:3, 0.5 M ammonium sulfate solution, 0.25 M, 0.5 M and 0.1 M potassium bromide solution, and phosphate buffer pH 2.5 in a twin-trough chamber without chamber saturation. Detection by spraying with 1 % iron chloride solution, 0.5 % potassium permanganate and 3 % barium chloride solution 1:1, 1 % ninhydrin in ethanol, 2 % phosphomolybdic acid in ethanol, and 5 % potassium dichromate in concentrated sulfuric acid. The study shows that the quality of separation depends to a large extent on the mobile phase, and selectivity is achieved by varying the composition of the mobile phase.
Thin-layer chromatographic procedure for the identification of preservatives in cosmetic products. J. Chromatogr. 410, 395-411 (1987). TLC of 88 preservatives on silica and alumina with ethyl acetate - diisopropyl ether - 96% ethanol - 25% NH3 55:30:10:2. Detection under UV 254 nm and by spraying with six reagents. Investigation of the retention behavior and the detectability of the preservatives, of which 74 were characterized. Detection limit, in the concentration range of 0.1%.
Z. Lebensm. Unters. Forsch. 206, 99-102 (1998). TLC of phenolic compounds on silica gel with a mixture of chloroform - methanol - water 63:35:10. Visualization by spraying with a solution of ferric chloride and potassium ferricyanide. Compounds with antioxidative activity were visualized after spraying with a solution of b-carotene and linoleic acid and observing the delay in bleaching of the b-carotene.
J. Planar Chromatogr. 23, 339-342 (2010). HPTLC of saccharin in foodstuffs (e. g. cola drinks, lemon juices, betel nut powder, mouth fresheners, ice candy, and tabletop sweeteners) on silica gel with chloroform - methanol - acetic acid 64:35:1 or acetone - isopropanol - acetic acid 60:39:1. Quantitative determination by absorbance measurement at 230 nm. Linearity was between 250 - 1250 ng/µL. The limit of detection and quantification for saccharin were 40 and 130 ng, respectively. Mean recovery from spiked samples was 102.3 % for cola drinks and 98.8 % for lemon juices. Relative standard deviation (% RSD) for cola drinks, lemon juices, ice candy, mouth freshener, betel nut powders, and tabletop sweeteners were 2.1, 4.2, 3.4, 3.0, 4.9, and 4.1 %, respectively.
Sz. Nyiredy, A. Kakuk (eds.): Planar Chromatography 2000, Lillafüred, Hungary, 24-26 June 2000, Res. Inst. for Med. Plants, p. 205-217. TLC of cetyldimethylbenzil ammonium chloride, cetyltrimethyl ammonium bromide, tributylmethyl ammonium hydride, laurylpyridium chloride, distearyldemethyl ammonium, benziltrimethyl ammonium hydride, ATO-368, AT-196, n-dodecilamine, AT22-300 on aluminum oxide with chloroform - NH3 - methanol 8:1:1 and on silica gel G with ethyl acetate - methanol - NH3 13:3:4 up to 15 cm. TLC of other quaternary ammonium salts and tertiary amines on silica gel G with chloroform - pyridine - methanol 4:3:3 for 150 min (this was the best system for separation of quaternary ammonium salts) or 5:3:2.
XI. Thin-layer chromatographic fractionation of Ames mutagenic compounds in chlorin-treated 4-methylphenol solution. J. Chromatogr. 360, 137-159 (196(6). TLC of Ames mutagenic compounds on silica with acetone - hexane 1:1. Detection under UV light. TLC of one of the 6 fractions on polyamide with chloroform. Examination of the fractionated components for mutagenicity by means of Ames assays, and identification by GC-MS.
