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.

Lipids 17, 448-452 (1982). Purification of hexadecyl cholesteryl ether by silica column chromatography for removing the majority of unreacted hexadecylmethane sulfonate and dihexadecyl ether by-product. TLC on silica with hexane - ether acetic acid 80:20:1. Typical overall product yield 60-80 % of the theory. Product resistant to acid hydrolysis in 7 % HCl in methanol for 4 h at 60 °C, conditions that hydrolize cholesteryl oleate.
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.
J. Planar Chromatogr. 4, 360-364 (1991). Description of a multidimensional approach to the coupling of HPTLC with capillary GC for the separation of the components of Matricaria chamomila. Multiple development on silica gel plates using solvents of different polarity and selectivity enables the separation of the components into various chromatographic zones, differing in the polarity of their constituents.
Chinese J. Pharm. Anal. (Yaowu Fenxi Zazhi) 16, 154-157 (1996). TLC on silica with a) petrol ether - hexane - ethyl acetate - ethanol 2:8:5:2, b) petrol ether (60 - 90 °) - hexane - ethyl acetate - ethanol - NH3 2:4:10:10:1. Detection by spraying with potassium iodobismuthate reagent. Quantification by HPLC after elution.
II. Calibration methods concerning quantitative hydrocarbon-group type analysis. J. Chromatogr. Sci. 36, 487-494 (1998). Use of TLC-FID for the hydrocarbon group type analysis of fossil fuels using internal normalization method. Investigation of repeatability, linear intervals and sample load ranges for quantitation towards different products covering a broad range of boiling points and chemical fractionalities in the field of fossil fuels. Comparison of the results with those obtained using external standard calibration. Validation of the method with TLC-UV scanning.
