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. Chin. Trad. Med. (Zhongguo Zhongyao Zazhi) 15, 483-484 (1990). TLC of benzoic acid on silica with petrol ether - ethyl acetate - acetic acid 20:1:1. Quantification by densitometry at 230 nm.
J. Chromatogr. 555, 239-245 (1991). HPTLC of abscisic acid on silica with toluene – ethyl acetate – acetic acid 25:15:2. Quantification by densitometry at 270 nm. Also HPLC. Comparison of the two methods.
J. Pharm. Biomed. Anal. 9, 717-723 (1991). TLC of antibiotic metacycline and its major impurities oxytetracycline, 4-epimetacycline, doxycycline, 2-acetyl-2-decarboxamidometacycline and 6-epidoxycycline on silica pretreated with EDTA/sodium hydroxide with dichloromethane – methanol water 58:35:7.

10: Effect on reproducibility of the relative positions of the spots and scanning slit. J. Planar Chromatogr. 5, 164-168 (1992). Demonstration that the most significant contribution to statistical errors in TLC arises from errors in positioning as a result of unequal and inhomogeneous distribution of samples on the stationary phase, and irregular relative positioning of slit and spot during a scan.
Biomed. Chromatogr. 6, 141-142 (1992). TLC of theophylline, diprophylline and proxyphylline on silica with chloroform - ethanol - formic acid 19:1:2. Detection under UV 254 nm. Quantification by densitometry at 275 nm. Second degree polynomial function over the range 40 - 200 ng for theophylline, 60 - 300 ng for diprophylline and proxyphylline.
