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. 9, 404-412 (1996). Discussion of the theoretical basis of migration of zones under conditions of stepwise gradient development. Depending on the relationships between retention and eluent composition, zone migration can be simulated by use of computer software which finds the gradient program corresponding to the optimum positions of the spots on the final chromatogram. A review of stepwise gradient TLC indicates that most plant extracts can be analyzed on silica or other polar adsorbents developed with binary nonaqueous eluents containing e.g. heptane, chloroform, ethyl acetate, and methanol. The use of stepwise gradient development results in a marked increase in separation efficiency. Investigated extracts are Taxus media, Cortex frangula, Rhizma rhei, Herba convallaria.
