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.
Chromatographia 71 (9-10), 907-911 (2010). Description of four-stage TLC, a new version of multidimensional (multi-stage) planar chromatography. In the first stage a multicomponent mixture is fractionated into three groups of chromatographic zones (fractions) by TLC where the adsorbent is deposited on an aluminum foil. In the second stage, the TLC plate is dried and cut by scissors into three narrow strips containing the separated fractions. In the next stages the isolated fractions on each of these strips (“daughter” plates) are separated into individual components with an appropriate mobile phase and by using a solvent flow perpendicular to the flow of the mobile phase. The practical application of the method is shown using as an example the separation of a mixture of dyes. The method can be expanded for separation of mixtures containing four or more fractions. This four-dimensional version of multidimensional TLC was carried out on plates with both open (conventional) and closed adsorbent layers.
Chinese J. Sci. & Technol. Review 17, 220-221 (2013). Zhihe Piba Keli pill is a TCM compound for the treatment of cough. For quality control, microemulsion TLC of Stemona sessilifolia (Miq.) Miq., Morus alba L. and Cynanchum glaucescens (Decne.) Hand.-Mazz on polyamide thin-films with (SDS - n-butanol – n-heptane 2.7:6.3:1.0) – formic acid 9:1, detection at UV 366 nm. Demonstration by applying to real life samples indicated that the procedure was suited for quality control.
J. Planar Chromatogr. 30, 405-410 (2017). HPTLC of 200 hydrocarbons containing condensed aromatic rings on silica gel with n-hexane and n-heptane. A magnetic field at constant inductivity (0.44 T), generated by a pair of permanent magnets perpendicular to the direction of chromatogram development was used to investigate its influence in the retention of substances.
J. Liquid Chromatogr. 8, 1225-1238, (1985). Investigation of the separation efficiency of various TLC techniques using a horizontal sandwich tank for continuous elution with a glass distributor. Complex extracts of camomile flowers (Azulane) were used as test mixture and the number of separated spots as the measure of efficiency.
Fresenius Z. Anal. Chem. 321, 556-558 (1985). Description of sequential centrifugal layer chromatography (SCLC), a new technique for preparative separation of isomers and other substances. TLC of 5 bipyridyl isomers on silica with 1.9 % tetrahydrofuran -1.59 % dioxane -1.39 % methoxyethanol -95.12 % hexane. Detection by UV 254 nm.
(Chinese). Chinese J. Chromatogr. 6, 24-26 (1988) (Sepu). Brief description of several techniques used in TLC of complex natural mixtures, including „hole-linear“ development, layer modifications, ionpair TLC, in situ derivatization, and others.
Alteration of spot profile in displacement thin-layer chromatography. Chromatographia 27, (1989).Investigation of the migration of spots in displacement development on silica. Study of the use of spacers and carriers. Demonstration of the effects of the presence or absence of the additive substances in the carrier.
J. Planar Chromatogr. 3, 6-9 (1990). HPTLC separation of 24 pesticides with the AMD-technique. Two 20-step elution gradients based on dichloromethane and on tert butyl methyl ether were tested. Using HPTLC silica gel layers of 100 µm instead of 200 µm and reducing the running distance increments from 3 mm to 1 mm, both sensitivity and speed of the procedure were increased. Scanning by adsorbance at 200, 220, 240, 260, 280 and 300 nm (multiwavelength).
