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. The saved items can be printed to PDF using the print function of your web browser.

      HPLC, TLC, and first-derivative spectrophotometry stability-indicating methods for the determination of tropisetron in the presence of its acid degradates
      L.S. ABDEL-FATTAH, Z. EL-SHERIF, K.M. KILANI, Dalia A. EL-HADDAD* (*National Organization for Drug Control & Research, 6&7 AboHazem St, Pyramids, P. O. Box 29, Giza, Egypt; daliaelhaddad@hotmail.com)

      J. AOAC Int. 93, 1180-1191 (2010). TLC of tropisetron and its acid-induced degradation products on silica gel with methanol - glacial acetic acid 223 with chamber saturation for 45 min. Detection under UV light at 254 nm. Quantitative determination by scanning at 285 nm. The hRf values were 44, 84, and 92 for tropisetron and degradates I and II, respectively. Linearity was between 1 and 10 µg/zone. Mean accuracy was 100.2 %. The precision was 0.64 %.The limit of detection and quantification for tropisetron was 0.26 and 0.80 µg/zone, respectively. The intraday and interday precisions were evaluated by assaying freshly prepared samples of tropisetron in triplicate concentrations, i. e. 3, 5, and and 9 µg/zone, resulting in 99.8 %, 100.3 %, and 100.4 %, respectively, for interday precision and 99.7 %, 100.2 %, and 99.7 %, respectively, for intraday precision (with a precision of 0.9 %, 0.6 %, 0.8 % and 0.6 %, 0.4 %, 0.6 %, respectively).
