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

Merck KGaA (Ed.): Chromatographie - Chronologie einer Analysentechnik - Praxis, Status, Trends, GIT Verlag mbH, Darmstadt, 222-230, ISBN 3-928865-21-8 (1996). Description of the experimental practice of the German standard DIN 38407, part 11, the field of usage and the steps of the whole procedure. Reasons for the determination limit of the procedure of 50 ng/L are given. Critical points and factors of influence are demonstrated during handling of the samples after sampling, during solid phase extraction, concentration of the eluate and AMD chromatography. The stepwise confirmation of positive results and thereby the flexibility of the method are shown.
J. Planar Chromatogr. 19, 85-86 (2006). TLC of methomyl on silica gel with benzene - ethyl acetate 3:2 in a presaturated TLC chamber. After drying the plate was sprayed with 1 % phloroglucinol solution then with 50 % hydrochloric acid. The plate was heated at 100 °C for 5 min. Detection limit of the pink-violet spot was 5 µg.
J. Planar Chromatogr. 20, 341-345 (2007). HPTLC of octachlorodipropyl ether on silica gel prewashed with chloroform - methanol 1:1 in an unsaturated twin-trough chamber with toluene - acetic acid - water 20:20:1. Detection by spraying with silver nitrate - 2 M ethanolic potassium hydroxide, followed by heating for 30 min at 120 °C, overspraying with 1 % silver nitrate in 30 % nitric acid, and exposure to UV light for approximately 15 min. Densitometric evaluation of absorbance at 399 nm.
J. Planar Chromatogr. 22, 133-135 (2009). HPTLC of monocrotophos on silica gel with chloroform - acetone 7:3 with chamber saturation. Detection by spraying with 20 % sodium carbonate followed by acidic methanolic iron chloride reagent. Evaluation of purple spots, while organophosphorus, organochlorine, carbamate, and pyrethroid insecticides were not detected as purple spots. Alkaline hydrolysis of monocrotophos yields one molecule each of O,O-dimethylphosphoric acid and N-methylacetoacetamide. After acidiification N-methylacetoacetamide yields the enol form of monomethylamide which reacts with ferric ions to a purple complex. The detection limit for monocrotophos is 0.5 µg/zone.
Encyclopedia of Chromatography Third Edition 1, 234-237 (2009). The author describes the combination of TLC or HPTLC with bioluminiscence detection for the effect-directed analysis (EDA) of bioactive zones on the layer. Specifically, bioactivity screening of complex mixtures by separation on HPTLC plates followed by dipping into a solution of the bioluminescent bacteria Vibrio fischeri is described.
J. AOAC Int. 93, 1748-1756 (2010). TLC of 35 pesticides on silica gel with ethyl acetate - n-heptane 2:3 in a horizontal chamber. Quantitative determination by absorbance measurement in the range of 200 to 360 nm using a DAD densitometer. The identity of the analytes was confirmed by UV spectra comparison of samples and standards. LOD and LOQ were 230 and 700 ng/zone for clofentazine and 160 and 490 ng/zone for chlorfenvinphos. These two pesticides were detected with the highest frequency in water samples.
J. Planar Chromatogr. 27, 299-314 (2014). 2D-HPTLC of 115 toxicological relevant drugs in serum or blood on silica gel with different solvent mixtures. Quantitative determination by absorbance measurement at different wavelenghts. The 2D-HPTLC method provided significant qualitative and quantitative improvements related to separation efficiency, comparable with HPLC-DAD, GC-MS and LC-MS.
J. Planar Chromatogr. 29, 388-390 (2016). HPTLC of dimethoate from post mortem viscera on silica gel with hexane - acetone 4:1. Detection by spraying with freshly prepared sodium nitroprusside solution (1 % sodium nitroprusside in 2 N sodium hydroxide solution prepared with especially sulfide-free distilled water). The hRF value for dimethoate was 88.
