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. Chromatogr. 642, 455-458 (1994). Description of thorium nitrate-impregnated silica layer for the separation of Zn, Cd, Ti, Hg from sea water and industrial waste water. Investigation of the interference of some common pesticides with the separation and the detection limits for the toxic metals.
Analyst 120 (5), 1427-1432 (1995). TLC and clean-up of the rare earth element group on cation exchanger in combination with ICP-AES. Detection limits, 0.25 - 5.0 ppm. Discussion of the possibility to use TLC in combination with other methods of element determination.
J. Planar Chromatogr. 11, 295-299 (1998). 2D-TLC of twenty inorganic cations on cellulose with1) 1-butanol saturated with a 1:1 mixture of 3 M nitric acid and 1 M HCl and 2) methanol - 36% HCl 10:3. 22 color reagents were used for detection. The twenty cations were chosen from the group of inorganic cations studied in the systematic qualitative analysis in introductory undergraduate chemistry courses.
J. Planar Chromatogr. 15, 367-370 (2002). 2D-TLC as screening method for Al, Cr, Cu, Ni, Mg, Zn, Mn, Pb, Sn, and Fe in honey with different mobile phases and detection reagents. The best separation was achieved on cellulose with acetonitrile - hydrochloric acid - water 73:15:12 in the first direction and 2-pentanol - acetonitrile - hydrochloric acid 3:2:5 in the second direction. A mixture of quercetin and dimethylglyoxime (prepared by dissolving 0.1 g quercetin in 100 mL 2-propanol and 1.0 g dimethylglyoxime in 100 mL ethanol, with dissolution by heating), and exposure to ammonia vapor was used for the visualization of the spots. This reagent mixture produced intensely colored spots for all the ions tested and enabled their identification at concentrations ranging from 50 to 1000 ng per spot. Simple, efficient and rapid method.
Acta Chrom. 11, 171-182 (2001). The chromatographic behaviour of some cations (Ni2+, Co2+, Cd2+, Cu2+, UO22+, VO2+, Fe2+/3+, Al3+, Th4+, Mo6+, W6+, Pb2+, Hg+/2+, Bi3+, Ag+, and Tl+) and anions (CrO42-, Cr2O72-, IO3-, IO4-, BrO3- SCN-, Fe(CN)63-, NO2-) was examined on layers prepared from 1:9 mixtures of a synthetic inorganic ion-exchanger (stannic arsenate or tin(IV) molybdosilicate) with silica gel, alumina, or cellulose with 1 % methanolic tri-n-butyl phosphate – 1 M aqueous formic acid 1:4 as mobile phase. Several binary cation separations of analytical interest were achieved. The metal ions were detected by use of conventional spot-test reagents. Separation of IO3- from NO2- and BrO3- under the same conditions, detection with 0.2 - 0.5 % diphenylamine in 2 M H2SO4. For quantitative determination the region corresponding to IO3- was isolated from the plate and extracted with 1.0 M hydrochloric acid. 1 % potassium iodide and conc. hydrochloric acid were added to the extract and the mixture obtained was titrated against Na2S2O3.
J. Liquid Chromatogr. 14, 3283-3300 (1991). TLC of 18 anions on alumina and alumina – silica gel 1:1, 1:2, 2:1 with mixed acidic organic solvent systems containing formic acid. Discussion of the chromatographic behavior. Investigation of the effect of transition metals on Cl– - Br– - I– and NO2– – NO3– separations.
VII. Thin-layer chromatography of cobalt (III) complexes. J. Chromatogr. 675, 271-275 (1994). TLC of a variety of inert cobalt (III) complexes of different charges on silica with aqueous salt solutions. Discussion of the relationship between the degree of adsorption of the cationic complexes on negative silica and the charge and charge distribution of the complex ion, and between Rf values and charges of complexes.
