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.

      The modification of pressurized planar electrochromatography chamber in respect of reduction of dead volume in the separation system
      R. GWARDA*, T. DZIDO (*Department of Physical Chemistry, Chair of Chemistry, Medical University of Lublin, 4a Chod?ki Street, 20-093 Lublin, Poland, radoslaw.gwarda@umlub.pl)

      J. Planar Chromatogr. 29, 72-76 (2016). Pressurized planar electrochromatography (PPEC) of peptides on RP-18 with water – methanol 3:7, an electrical potential of 400 V and a pressure applied of 20 bar. Detection by dipping into 2 % ninhydrin solution in acetone – methanol – glacial acetic acid 25:25:2. The improvement of the PPEC equipment was related to the application of a single Teflon sheet placed beneath both the partition and the cover, resulting in the elimination of the dead volume during the separation process.

      Thin-layer chromatogram development with a moving pipette delivering the mobile phase onto the surface of the adsorbent layer
      Aneta HAŁKA-GRYSIŃSKA*, K. SKOP, A. KLIMEK-TUREK, M. GORZKOWSKA, T.H. DZIDO (*Department of Physical Chemistry, Medical University of Lublin, Chodźki 4a, 20-093 Lublin, Poland)
      J. Chromatogr. A 1575, 91-99 (2018). Presentation of a new prototype for the development of thin-layer chromatograms using flexible mobile phase dosage onto the surface of the layer by moving pipette combined with precise syringe pumps. The pipette is moved by a computer controlled, modified 3D printer mechanism. Delivery of the mobile phase to the layer was equal to or lower than that of conventional development. The chromatograms are developed at optimal mobile phase velocity, which is adjusted to the absorption rate of the layer. As there is no excess eluent on the surface of the layer, a higher performance of the chromatographic system is obtained. By development with constant linear mobile phase velocity, the relationships the plate height vs. mobile phase linear velocity obtained with planar chromatography driven by capillary forces are investigated and reported. Also investigated were the relationships between plate height and mobile phase linear velocity, the influence of the variance of the starting zone related to the total peak variance, and the influence of narrowing the starting zone on the performance of the whole system. There is a significant influence of the starting zone variance on the total peak variance, and therefore of the starting zone size on the plate height of the system.

      Effect of the external pressure on the efficiency of off-line and on-line OPLC

      J. Planar Chromatogr. 3, 121-125 (1990). Demonstration of the variability of the external pressure in OPLC technique. In fully off-line OPLC for single development, increasing external pressure yields a more efficient separation, high peak capacity, and increased sensitivity, whereas, under conditions reported, on-line OPLC does not provide the same efficiency increase.
