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

      University Halle-Wittenberg, 06099 Halle, Germany, mathias.reisberg@pharmazie.uni-halle.de)

      CBS 113, 13-15 (2014). HPTLC of glycosylceramide Glc-d18:2 h16:0 from wheat germ and standards squalene, cholesteryl oleate, glyceryl trioleate, linoleic acid, ß-sitosterol, and ß-sitosterol glucoside on silica gel in the AMD 2 with a 18-step gradient modified from Opitz et al. (Chromatographia 73 (2011) 559), methanol replaced ethanol, and the mobile phase composition was changed slightly (pre-conditioning with 4 M acetic acid before each step, drying time 1.5 min, development duration 3 h and solvent consumption 200 mL). Detection by dipping in copper sulfate phosphoric acid reagent for 20 s and heating at 130 °C for 15 min revealed grey-brown bands. Densitometry evaluation by absorbance measurement at 546 nm. For Glc-d18:2 h16:0, regression analysis showed a polynomial relationship with coefficients of determination (R2) from 0.995 to 0.999 (n=3, 50 - 1000 ng/band). LOD (S/N 3) and LOQ (S/N 10) of Glc-d18:2_x000D_ h16:0 were 10 ng/band and 50 ng/band, respectively (n = 6).

      Some aspects and examples of automated multiple development (AMD) gradient optimization
      G. LODI*, A. BETTI, E. MENZIANI, V. BRANDOLINI, B. TOSI, (*Dipartimento di Chimica, Universita die Ferrara, Via Borsari 46, I-44100 Ferrara, Italy)

      J. Planar Chromatogr. 4, 106-110 (1991). Presentation of 3 examples of optimization of AMD gradients: 1 + 2: Universal gradients optimized for the separation of phenolic compounds spanning a wide polarity range on diol layers, 3: Optimization for the separation of organochlorine pesticides on silica spanning a low polarity range. Preliminary isocratic developments of selected standards were performed with binary solvent mixtures in order to set up the gradients. The retention data (as plots of Rm values against solvent composition) can be used for the choice of the gradient components and gradient boundaries.

      AMD (Automated Multiple Development) - Anwendungen und online Kopplungen mit reversed phase HPLC
      K. BURGER, (Zentrale Analytik, Bayerwerk, Gebäude Da 5, 41538 Dormagen, Germany)

      Teil 2: Die online Kopplung HPLC - AMD. (AMD (Automated Multiple Development); application and online coupling with reversed phase HPLC. Part 2: Online coupling HPLC-AMD). Dünnschicht-Chromatographie InCom Sonderband 1996, 53-71. Online coupling of HPLC and AMD is a two-dimensional separation system, where the completely different separation mechanisms of reversed-phase chromatography in a column and planar chromatography on silica are coupled. Online coupling of HPLC and AMD/HPTLC is capable of separating several thousand substances. With this system practical any number of pesticides in any kind of water sample can be quantified. Without clean-up, interferences of the matrix are reduced to nearly zero. The method is demonstrated by the analysis of a surface water sample spiked with pesticides.
