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.

      Validation of an HPTLC method for determination of caffeine
      I. VOVK, A. GOLC-WONDRA, M. PROSEK*, (*Nat. Inst. of Chem., Lab. of Food Chem., Hajdrihova 19, 1000 Ljubljana, Slovenia)

      J. Planar Chromatogr. 10, 416-419 (1997). Complete validation of an HPTLC method for the quantitative determination of caffeine in Coca-Cola has been performed according to ICH guidelines, taking into consideration the special features of the method. The validation parameters were: selectivity, stability of the analyte, linearity, precision, (repeatability and intermediate precision), and robustness. Quantification with a slit-scanning densitometer and with an image-analyzing system. The same plates were used in both validation procedures to reveal possible differences between the different modes of quantification. The results obtained show no difference in validation parameters - because all the results are within the range of criteria recommended for TLC validation. Both systems can be used for quantitative evaluation of TLC plates.

      HPTLC-UV/MS of caffeine in energy drinks
      M. SCHULZ (Merck KGaA, MM-LAR-A, Frankfurter Str. 250, 64293 Darmstadt, Germany, michael.schulz@merckgroup.com)

      CBS 113, 9 (2014). HPTLC of caffeine in energy drinks (applied neatly without sample preparation) on silica gel MS-grade with 2-propanol – n-heptane – water 7:3:1. Detection under UV 254 nm and by dipping into anisaldehyde reagent. Quantitative evaluation by absorbance measurement at 273 nm. The hRf of caffeine was 55. For confirmation of results, zones were eluted with the TLC-MS Interface (acetonitrile – water 19:1 with 0.1 % formic acid, flow rate 0.1 mL/min) and directly transferred to a mass spectrometer and measured in ESI(+) full scan mode (m/z 100 – 500).
