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.
J. Planar Chromatogr. 2, 262-267, (1989). Preconcentration procedure and HPTLC separation of 13 pesticides (phenylureas, carbamates, triazines, and other N-heterocyclic compounds) using HPTLC, development by a 30-step gradient (methanol - chloroform) using the AMD technique; detection by measuring the UV reflectance at 6 wavelengths ( = 190, 220, 240, 260, 280, and 300 nm). CV ± 2,2% at a concentration range between 20 and 500 ng.
J. Planar Chromatogr. 2, 180-189 (1989). Properties of the sample and matrix effects, that affect quantitative TLC using scanning densitometry are discussed. The sorbent matrix influences the shape of calibration curves, and impurity gradients, resulting from contamination of the layer or application of derivatizing reagents are common sources of baseline instability. Chemical reactions catalyzed by the sorbent layer, which may also involve oxygen or light, are a source of sample instability. Fluorescence quenching and fluorescence enhancement effects can influence the reliability of quantification in the fluorescence mode. Some practical examples of the effects are discussed. Comparison of HPLC and TLC.
J. Planar Chromatogr. 3, 38-41 (1990). HPTLC of phosphatidyl cholin, oleic acid, cholesterol, triolein and cholesterol on preadsorbent silica gel with a new solvent system by double ascending development in saturated chambers.
