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.

      Anal. Bioanal. Chem. 391, 2219-2225 (2008). HPTLC/TLC of testosterone and derivates (methyltestosterone, testosterone propionate, testosterone isobutyrate, testosterone phenylpropionate, testosterone isocaproate, testosterone enanthate, testosterone caprate on silica gel, RP-18W and aluminium oxide with a whole range of binary mixtures such as methanol/water, acetonitrile/water, methanol/dichloromethane and acetone/hexane 0 – 100 % on the effect of temperature ranging from -20 to +60 °C under saturated and unsaturated chamber conditions. Detection by dipping in 10 % methanolic phosphomolybdic acid, followed by heating at 100 °C for 10 min. Evaluation under UV 366 and 254 nm. The best separation was observed on RP-18W with methanol/water mobile phases.
