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.

      High-performance thin-layer chromatography of phenyl-ethylamines and phenolic acids on silanized silica and on ammonium tungstophosphate
      L. LEPRI, P.G. DESIDERI, D. HEIMLER

      J. Chromatogr. 347, 303-309 (1985). Study on HPTLC behaviour of phenylethylamines and phenolic acids on silanized silica impregnated with N-dodecylpyridinium chloride, or with dodecylbenzenesulfonic acid. The presence of KCl makes the spots more compact. The presence of 1 or more OH groups in the molecule decreases the retention of the compounds, whereas an opposite behaviour occurs with replacement of a phenolic group with an OCH3 group. Secondary amines are more strongly retained than primary amines. The N-CH3, groups increase the affinity of the compounds towards the exchanges in the order: primary amine secondary amine tertiary amine. Phenylethylamines, phenolic acids, silanized silica, ammonium tungstophosphate

      Monodansyl cadaverine as a fluorescent marker for carboxylic acids - in situ prechromatographic
      A. JUNKER-BUCHHEIT, H. JORK*, (*Univ. des Saarlandes, Fachbereich 14, D-6600 Saarbrücken, FRG)

      J. Planar Chromatogr. 2, 65-70 (1989). For qualitative analysis monodansyl cadaverine (MDC) was employed without further purification. Column-chromatographic purification is recommended for the quantification of short chain carboxylic acids. For in situ derivatization the carboxylic acid sample solutions were applied to the HPTLC plates as bands with a maximum length of 10 mm. These were then „overlayed“ with MDC solution containing N,N’-dicyclohexylcarbodiimide to activate the acids. Short-chain carboxylic acids were separated on normal silicagel phases with toluene - ethyl acetate - ammonia mixtures as mobile phase. Stepwise and gradient developments allow the baseline separation. Long-chain carboxylic acids are better separated on RP-18 phases with acetonitrile-tetrahydrofuran mixtures and methanol as mobile phase.
