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.

      J. China Assoc. Instr. Anal. 8, 6-14 (1989). A review with 15 references of some recent developments in instrumental TLC techniques aiming at increasing the separation efficiency based on existing layers, such as gradient elution in normal phase, multidimensional separations by coupling gradient-elution reverse-phase HPLC with AMD normal phase gradient elution. Description of applications to phospholipids in emulsifiers, sulfonamides in feed, plastic prepolymerizate and pesticides in drinking water.

      Part II. Multi-stage development. J. Chromatogr. 635, 283-289 (1993). Presentation of a theoretical model of gradient multiple development as a basis for the optimization of separation by planar multi-step development and AMD and a computer program for the calculation of final Rf values for multi-stage development in the gradient mode for known retention vs. eluent composition relationship. Discussion of the influence of various parameter on the final Rf values. Comparison of the predicted and experimental Rf values.

      Identification and quantification of antioxidants in PVC stabilizers
      D. SCHERIER*, R. SCHMIDT, C.S.L. WALTON, (*Henkel KGaA, 40191 Düsseldorf, Germany)

      J. Planar Chromatogr. 8, 439-443 (1995). HPTLC of 12 PVC antioxidants (i.a. bisphenol A, AO2 - AO10, BHT, AO12); identification was based both on isocratic development and automated multiple development. The isocratic screening method is a three-part TLC system with a basic separation method and two group-separation methods. Automated multiple development achieves identification with a single chromatogram. Quantification was performed using three of the twelve antioxidants as examples with mixtures of petrol ether and ether containing acetic acid (1 mL). A) 32 for the basic separation, b) 11 for group I separation and c) 191 for group 2 separation. Detection under UV 254 nm. Mobile phase for AMD consisted of n-heptane and diethyl ether. Quantification by densitometry at 258 nm (absorbance), at 366 nm (fluorescence). Recovery of e.g. bisphenol A was 97% with a relative standard deviation of 2.1%.

      Analysis of polycyclic aromatic hydrocarbons

      CBS 83, 6-7 (1999). HPTLC-AMD of PAHs in liver and lung of animals exposed to contaminated soil on RP-18 with a 14-step gradient from acetonitrile to methanol - water 91. Quantification by fluorescence measurement at 313/>400 nm and 254/>400 nm, respectively. Strict linearity (r2 > 0.99 on 5 measuring points) was proven. Coefficient of variation was found to be < 5 %, and recoveries between 55 and 70 % were given. Limits of detection was determined to be 0.2 to 2 ng/g sample.
