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.

A comparative study. J. Chromatogr. 635, 165-170 (1993). Two-dimensional TLC maps of dansyl chloride-, dabsyl chloride- and 7-chloro-4-nitrobenzoxazole - derivatised amines on silica with 9 solvent systems. Evaluation of some factors which influence sensitivity. Recommendation of dansyl chloride as the reagent for chromatographic analysis of complex mixtures of biogenic amines.
Anal. Letters 31, 475-489 (1998). HPTLC of plant tissues, dansylated in a microwave oven, on silica with chloroform - triethylamine 2:1. Quantitation by in situ densitometry at 338/>502 nm. Detection limit 1.8 - 3.0 ng. Precision 0.75-1.39%.
CBS 93, 5-7 (2004). HPTLC of N,N-diethylethane-1,2-diamine in metoclopramide finished products on silica gel with 32 % ammonia - methanol - dichloromethane 3:15:80 over 40 mm with chamber saturation. Detection by dipping in 0.2 % ethanolic ninhydrin solution for 1 s, followed by drying at 120 °C for 5 min. Quantitative determination by absorbance measurement at 480 nm and evaluation of peak area with polynomial regression. The correlation coefficient of the calibration curve is 0.9995, the residual standard deviation 2.19 %. Intermediate precision is 1.65 %. Recovery for 0.2-1.0 % impurity is 100.5 %. Limit of quantitation is 0.05 % impurity.
Scholars Research Library 2(3), 163-167 (20100. TLC on silica gel with n-butanol - water - methanol - ammonia 8:1:1:2 with chamber saturation for 10 min. The hRf value was 33 for gatifloxacin and 89 ambroxol HCl. The method was linear in the range of 100-600 ng/band for gatifloxacin and 12.5-62.5 ng/band for ambroxol HCI. The recovery was 99.3-100.3 %. Densitometric evaluation at 310 nm.
