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.
Acta Chromatographica No. 7, 149-158 (1997). TLC of nitro- and azaarenes (nitronaphthalene, nitrofluorene, nitroanthracene, nitropyrene, quinoline, azafluorene, benzo(h)quinoline) on silica with acetonitrile - water 9:1 for nitroarenes and methanol - water for azaarenes. Detection under UV 254 and 366 nm and by spraying with specific reagents for the detection of functional groups: 15 % tin(II) chloride in 36 % hydrochloric acid and p-dimethylaminobenzaldehyde for nitroarenes and Dragendorff's reagent for azaarenes. Detection limit for nitroarenes 25 - 100 ng, for azaarenes 50 - 100 ng.
Proc. Intern. Symp. on Planar Separations Plan. Chrom. 3-11 (2003). HPTLC of pyrene on silica gel with hexane and on RP-18 with methanol - acetone 8:3 in a horizontal developing chamber. Densitometry at 198 to 610 nm after dipping in a solution of 3.8 g pentane sulfonic acid in 20 mL water.
CBS 81, 6-7 (1998). HPTLC-AMD on silica gel with a gradient based on methanol – dichloromethane – n-hexane. Quantification by densitometry with absorbance measurement at 220 nm and fluorescence measurement at 366/>400 nm.
Wasser-Abwasser Forsch. 16, 132-135 (1983). Eindimensionale dünnschitchromatographiesch Trennung und fluorometrische Bestimmung von polycyclischen aromatischen Kohlenwasserstoffen aus Wasserproben. (One-dimensional thin-layer chromatographic separation and fluorometric quantification of polycyclic aromatic hydrocarbons in water samples). TLC of benzo(a)pyrene, benzo(h)fluoranthene, indeno(1,2,3-dc)pyrene, benzo(k)-fluoranthene, fluoranthene, benzo(g,h,i) perylene on acetylated cellulose with methanol - water - ether - dichloromethane 20:10:30:1.25. Fluorometry at 366 nm.
Chinese J. Petrol. Proces. (Shiyou Lianzhi) 24, 56-59 (1993). TLC of olefins on silica rods impregnated with silver nitrate, developed first with heptane, then with toluene. Detection and quantification by FID. Comparison of results with those from liquid-solid adsorption method.
J. Planar Chromatogr. 5, 205-206 (1992). TLC of decanal on silica with benzene. Visualization by exposure to iodine vapor or under UV 366 nm.
J. Planar Chromatogr. 28, 139-143 (2015). TLC of 16 polyaromatic hydrocarbons on RP-18 phase. In the first direction, the plate is developed twice with n-pentane at -20 °C, and in the second direction with acetonitrile - methanol - water 12:8:3:3. Both developments were carried out over a distance of 43 mm. Detection by chemiluminescence: a solution of 225 mg Bis(2,4,6-trichlorophenyl)oxalate dissolved in 45 mL of n-butyl acetate was prepared. 125 μL hydrogen peroxide 30 % were vigorously shaken with this solution for 20 min. The mixture is suitable for chemiluminescence measurements within a period of 48 h. The best results were observed when the plate was dipped in this solution for 1 s and dried until no light reflection could be seen on the surface. Then, the TLC plate was covered by a glass plate and measured for 1 min using a very light-sensitive CCD camera. The proposed chemiluminescence screening method is able to separate PAHs from PAH oxidation products and detects benzo[a]pyrene and perylene with a LOD of 95 pg/band for benzo[a]pyrene and 48 pg/band for perylene. Although these compounds were separated from all other PAHs in the standard, a separation of both compounds was not possible from one another.
Preliminary experiments. Chromatographia 23, 337-340 (1987). Investigation of the retention behaviour of 5 polycyclic aromatic hydrocarbons with nearly equal ionization potentials but different molecular polarizability. Normal and reversed-phase HPTLC with homologous series of hydrocarbons and n-alcohols as the mobile phases. Discussion of the electrostatic interactions operating in these chromatographic systems by studying the relationship between the log 1/Rf values and the molecular polarizability of solutes and solvents.
