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. Liq. Chromatogr. Relat. Technol. 31, 203-222 (2018). HPTLC of fluorometholone (1) and sodium cromoglycate (2) on silica gel with ethyl acetate – methanol 9:1. Quantitative determination by absorbance measurement at 240 nm. The hRf values for (1) and (2) were 65 and 12, respectively. Linearity was in the range of 0.1-24.0 μg/zone for (1) and 0.2-48.0 μg/zone for (2). The intermediate precision was below 1.1 % (n=9). The LOD and LOQ were 9 and 270 ng for (1) and 170 and 510 ng for (2), respectively. Average recoveries for (1) and (2) were 100.3 and 100.7 %, respectively.

J. Planar Chromatogr. 31, 297-308 (2018). HPTLC of zopiclone in the presence of its degradation products, namely, 7-oxo-6,7-dihydro-5H-pyrrolo[3,4-b]pyrazin-5-yl-4-methylpiperazine-1-carboxylate (hydrolytic DEG) and 5H-pyrrolo[3,4-b]pyrazine-5,7(6H)-dione (oxidative DEG) on silica gel with ethyl acetate – methanol – ammonia 33% 17:2:1. Quantitative determination by absorbance measurement at 303 nm. The hRF value for zopiclone was 44. Linearity was between 0.1 and 2 μg/zone. LOD and LOQ were 30 and 80 ng/zone. The intermediate precision was <2 % (n=3). Average recovery was 99.5 %.
