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.

      Variation of stationary phases in planar chromatography
      T.J. GOOD*, A.G. TAKETOMO, (*CERA, 14180F Live Oak Ave., Baldwin, Park, CA 91706, USA)

      J. Planar Chromatogr. 2, 383-386 (1989). TLC separation of dyes and plant pigments on different modified silica stationary phases (cyclic diols, cyanopropyl, carboxylic ester) with toluene, isooctane - methanol - diethylether 7:1:2 as mobile phase and three methods of development - traditional vertical tank, experimental horizontal sandwich apparatus and an experimental over-pressure device. - The variation of the stationary phase can be used to gain selectivity advantages in chromatographic separations.

      Improved Chromatographic clean-up of anabolics in bovine urine
      H.F. DE BRABANDER*, P. VANHEE, S. VAN HOYE, R. VERBEKE, (*Laboratory of Chemical Analysis of Food from Animal Origin, Vet. Fac.of the Univ. of Ghent, Casinoplein 24, B-9000 Ghent, Belgium)

      J. Planar Chromatogr. 2, 33-38 (1989). Two-dimensional TLC of anabolics on silica with 5 different solvent systems. Reference mixtures contained 2 - 20 ng of the steroids (zeranol, zearalenone, a-nortestosterone, medroxyprogesterone acetate, trenbolone, trebolone acetate). Alternatively a „4x4“ developing mode could be used. In this mode 4 samples are developed in two dimensions on one HPTLC plate. For inducing fluorescence reaction, the plates were dipped into a 5% sulfuric acid - ethanol solution for 30 s and then incubated at 95°C for 10 min. The fluorescence before and after heating was observed under UV 366 nm. The described method permit the routine detection of various anabolic residues in bovine urine at levels of 0.5 - 10 ppb. The recoveries are high (70 - 90%). Standard deviation were between 2 and 8%.

Optimization of mobile phase composition was carried out by using a comprehensive computer program written in HP BASIC 4 language. The separation of spots on the chromatograms showed agreement between predicted and experimental chromatograms.
