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. 28, 24-29 (2015). HPTLC of new derivatives of 1,2,4-triazole and thiosemicarbazide on RP-18W with 30 % acetonitrile and 40 % MeOH as organic modifiers, both in water, detection at UV 254 nm. 30 % provided the most close phase ratio in TLC and HPLC. The method can be used as a pilot technique for the anticipation of retention in HPLC.
J. Planar Chromatogr. 29, 281-286 (2016). HPTLC of newly synthesized cycloalkylspiro-5-hydantoins (derivates of 3-(4-substituted benzyl)-cyclopentanespiro-5-hydantoin, 3-(4-substituted benzyl)-cyclohexanespiro-5-hydantoin, and 3-(4-substituted benzyl)-_x000D_cycloheptanespiro-5-hydantoin) on RP-18 with varying content of methanol 50–90%. Multivariate analysis enabled the classification of the lipophilicity and structural properties of the investigated compounds.
various dyes on silica and cellulose stationary phases using a data mining approach
J. AOAC Int. 101, 1437-1447 (2018). Micro-TLC of 18 standard dyes (Amaranth, Bromophenol blue, Bromothymol blue, Patent blue V, p-Xylenol blue, Brilliant Black BN, Erythrosine, Fluorescein, Carmine, Naphthalene black 10B, Phenol red, Bromocresol purple, Sudan II, Sudan III, Sudan IV, Bromocresol green, Dimethyl yellow, and Methyl red) on silica and cellulose with different solvent mixtures (methanol – water and dichloromethane – methanol) in proportions varying from 0 to 100 %. Chromatographic parameters and quantum mechanics properties of each solute were used along with data mining to model the chromatographic behavior.
J. Chromatogr. Sci. 22, 538-547 (1984). Principal component analysis (PCA) with Rf values for 596 basic and neutral drugs in 4 eluent mixtures on silica. Two-component model explaining 77 % of the total variance. Each drug is characterized on a plane by two principal component scores. For the identification of unknowns the method provides a drastically reduced short list of possible candidates. The 4 eluent systems are: a) methanol - NH3 100:1.5, b) cyclohexane - toluene - diethylamine 75:15:10, c) chloroform - methanol 9:1, d) acetone.
J. Microchem. 32, 198-201 (1985). TLC separation of o-, m- and p-ethylphenol on silica with benzene - acetone 8:2 and of o-, m- and p-phenylenediamines on silica with butanol - acetic acid - water 4:1:5. Detection with 0.005 % aqueous new fuchsin solution
Application of a micro computer program to the thin-layer chromatographic separation of some diastereoisomers on silica. J. Chromatogr. 438, 219-224 (1988). TLC of 4 diastereoisomeric amino esters and isochromans on silica with 21 mobile phases composed of 2-6 solvents and selected by means of a microcomputer program based on Snyder’s displacement model. Discussion of the effect of the variation of the mobile phase on the relative retention of each diastereoisomeric pair and on the relative separation as predicted by theory.
J. Planar Chromatogr. 3, 24-33 (1990). Method for the estimation of partition coefficients of both neutral and basic PAH. RP-TLC of 63 compounds on C-18 and KC 18-bonded silica with mixtures of methanol – deionized water or methanol – 0.063 M phosphate buffer (pH = 7). RM data may be predicted from structural descriptors, such as molecular connectivities and calculated partition coefficients.
J. Planar Chromatogr. 5, 424-430 (1992). Investigation of the retention of higher fatty alcohols and acids in RPTLC with bonded alkyl stationary phases and water - methanol eluents. Adapting a theoretical approach introduced previously (T. Kowalska, Chromatographia 27, 628-630 (1989)), it has been possible to determine not only the contribution of the solutes’ methylene, hydroxyl, and carboxyl structural groups to overall retention, but also their effects on a mixed retention mechanism involving the chemically bonded alkyl groups and the remaining part of the solid matrix.
