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. The saved items can be printed to PDF using the print function of your web browser.
J. Planar Chromatogr. 21, 325-329 (2008). Development and systematization of nontraditional TLC methods, in which the chromatographic process occurs in a closed absorption layer on a standard TLC plate. The advantages and limitations of the methods were assessed and the expediency of their further development and wider use in practical TLC was proved.
J. Chromatogr. 302, 149-158 (1984). HPTLC of polycyclic aromatic hydrocarbons on different stationary phases with various mobile phases in several development modes, conventional, continuous, and multiple development. Reversed-phases in separation using RP-18 silica and methanol - water or methanol - water based ternary solvent system gave the best result.
IV.: Comparison of retention behaviour in gas-liquid, thin-layer and high-performance liquid chromatography. J. Chromatogr. 388, 161-177 (1987). TLC of organometalloid derivatives of amino alcohols on silica with solvent systems consisting of isopropanol and hexane. Detection by iodine vapor and wetting with water. Calculation of Rm values. Comparison of the retention behaviors in GC, TLC and HPLC.
I. Salting-out chromatography of organic compounds. J. Chromatogr. 406, 389-404 (1987). Study on the adsorption on cellulose of organic compounds from aqueous ammonium sulfate solutions. The adsorption increases with increasing concentration of ammonium sulfate for all compounds examined. Investigation of the relationship between RM values and the activity of ammonium sulfate. Conclusion: the mechanism of adsorption is a non-specific hydrophobic interaction.
J. Chromatogr. 475, 95-112 (1989). Studies of the characteristics of some commonly available precoated polar modified TLC plates, using normal and reversed-phase conditions with a series of butyrophenones and benzimidazol-z-ones as model compounds. Examination of the influence of different types of salts, salt concentration, organic modifier content, the use of ion-pair reagents and pH values of retention behavior.
J. Liquid Chromatogr. 14, 1435-1446 (1991). Screening for 140 drugs on silica with toluene - acetone - ethanol - NH3 45:45:7:3 and on RP-18 with methanol - water - hydrochloric acid 50:50:1. Evaluation of the combination for identification with the mean list length method: a value of 1.7 obtained for the present combination, and values of 2.5 and 5.5 for another TLC/RPTLC combination and a TLC/TLC combination, respectively (95% cumultative probability). Study on the influence of Rf correction on RPTLC reproducibility.
Laborscope 2, 5-7 (1997). HPTLC is growing in importance because of its cost effectiveness although it is an off-line system (only the individual steps of TLC are automated). Advantages of TLC are given. Devices for application, chromatography, detection and documentation are presented showing the state of the art in TLC. Also published in CLB 48, 292-293 (1997).
J. Planar Chromatogr. 17, 438-443 (2004). Proposals for general standardized HPTLC methodology: 1. Plate material (consistent material, prewashing, direction of development, activation of plates, influence of relative humidity). 2. Sample application (precise and accurate volume, solvent, position, spot or bandwise application). 3. Preparation and storage of mobile phases (stability, possible reaction). 4. Development (saturation, use of a twin-trough chamber, influence of the vapor phase, distance, drying). 5. Derivatization (dipping, spraying, heating). 6. Documentation of plates. 7. Labeling (plates, images). 8. Quantitative evaluation 8. Documentation of work.
