- 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.
Acta Chrom. 17, 261-271 (2006). TLC and HPTLC plates have been compared on the basis of theoretical plate number, resolution, linearity, development time, and limit of sensitivity for analysis of a multicomponent analgesic tablet in the fluorescence quenching mode and analysis of a five-component dye mixture in the visible mode.
J. Planar Chromatogr. 3, 10-14 (1990). Description of a new solid phase sample application method and application device. It enables regular sample applications in the entire cross section of the preparative layer with the advantage of in situ sample concentration and clean up. With the proposed device the sample can be applied to improve the starting situation for a preparative planar chromatographic separation, independent of whether the migration of the mobile phase is achieved by capillary action or forced flow phase is achieved by capillary action or forced flow (OPLC, RPC). Chromatography of crude plant extracts from leaves of Malva silvestris and roots of Heracleum sphondylium.
J. Planar Chromatogr. 19, 81-85 (2006). A simple device is proposed for chromatographic separation with a traditional plate under the condition of a closed adsorbent layer (TLC-CL). Compared with traditional TLC the new variant has certain advantages, it takes for example 20-30 % less time; the efficiency of TLC-CL was, however, usually less than that of traditional TLC.
J. Planar Chromatogr. 23, 415-419 (2010). The paper summarizes the classification and applicability of centrifugal layer chromatography and rotation planar chromatography (RPC). The combination of TLC with centrifugal force resulted in the introduction of centrifugal layer chromatography which was renamed rotation planar chromatography because the abbreviation CLC had been used for column liquid chromatography. In analytical RPC three development modes are possible - circular, anticircular, and linear. On-line and off-line sample application, separation, and detection can be combined. RPC is suitable for analytical, micro-preparative, and preparative separations. The term RPC covers five basic techniques: normal chamber, micro-chamber, ultra-micro chamber, column and sequential RPC. Most RPC methods are applicable to preparative separation of a single sample. Analytical RPC is rarely used.
electrochromatography of amino acids in systems with silica gel and water mobile phase
J. Planar Chromatogr. 29, 30-37 (2016). HPTLC and pressurized planar electrochromatography (PPEC) of 20 amino acids on silica gel with acetonitrile – buffer pH 3.2 (citric acid – disodium hydrogen phosphate 2.28:1.44) 1:1 for HPTLC and acetonitrile – buffer pH 3.2 4:1 for PPEC. PPEC separation was performed at a polarization voltage of 1.0 kV for 25 min. Detection by spraying with ninhydrin solution, followed by heating in a warm air stream.
J. Chromatogr. A 1530, 211-218 (2017). Development of a novel and cost-effective TLC method on cellulose (instead of silica gel) for authentication of selected fruit-based alimentary products. As authenticity markers the anthocyanins cyanin chloride, keracyanin chloride, pelargonidin chloride and delphinidin chloride were used. With TLC, the LOD and LOQ for cyanin were of 25 and 75 ng/zone, for keracyanin 55 and 166 ng/zone, for pelargonidin 47 and 140 ng/zone, and for delphinidin 171 and 513 ng/zone. With HPTLC the LOD and LOQ for cyanidin were 107 and 321 ng/zone, for keracyanin 189 and 566 ng/zone, and for pelargonidin 161 and 484 ng/zone (delphinidin was not detectable). Consequently, quantification of anthocyanes in the alimentary products by TLC allowed identification of more target compounds and in a higher number of alimentary products than by HPTLC. (Note that original HPTLC method in J Chromatogr A 1299 (2013) 105-118 was reported to be more sensitive (mainly 3-50 ng/zone) and with higher correlation coefficients of calibration curves (0.9993-0.9999) for 11 anthocyanins/-cyanidins than the HPTLC method that was reproduced in this paper.)

Investigation of chromatographic behaviours. Rf values found dependent on the concentrations of the two components in mobile phase, and type of stationary phase, as well as the structures and size of the individual molecules.
