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. The saved items can be printed to PDF using the print function of your web browser.
J. Planar Chromatogr. 32, 265-271 (2019). HPTLC of 24 anions on tri-n-butyl amine (TBA) impregnated silica gel with 13 mobile phases (methanol, dimethylformamide, diisopropyl ether, tetrahydrofuran, 2-propanol, dimethylformamide - methanol 1:1, dimethylformamide - diisopropyl ether 1:1, dimethylformamide - tetrahydrofuran, 1:1, dimethylformamide - 2-propanol 1:1, 0.1 M oxalic acid, 0.1 M tartaric acid, 0.1 M citric acid and 0.1 M succinic acid). The retention behavior was analyzed in aqueous and non-aqueous mobile phases. The hRF values were also correlated with their lyotropic numbers. 20 % TBA-impregnated silica gel was found very effective for binary and ternary separations of anions.
J. Planar Chromatogr. 23, 343-347 (2010). TLC and HPTLC of (derivatized) sulfide ions on silica gel with dichloromethane - methanol - diethyl ether - 25 % ammonia 40:5:5:1 in a horizontal chamber saturated for 20 min. Detection by using the methylene blue method, i.e. production of methylene blue by oxidative coupling of sulfide with N,N-dimethyl-p-phenylenediamine in the presence of iron(III) ions in acidic medium. Quantitative determination by absorbance measurement at 660 nm (method I), or analysis by TLSee software (method II). Response for both was a linear function in the concentration range of 20-100 pmol/zone. The LOD and LOQ were 10 pmol/zone (3.2 mg/L) and 20 pmol/zone (6.4 mg/L). The repeatability of both methods (%RSD) was 1.9-4.2 % for method I and 1.5-3.9 % for method II.
J. Planar Chromatogr. 13, 12-15 (2000). Examination of the retention behavior of iodide, iodate and periodate on silica gel, cellulose, alumina and kieselguhr with mixtures of 0.1 M NH3 and acetone as mobile phase. Alumina and 0.1 M NH3 - acetone 9:1 was best because it furnished more compact and well-resolved spots of the anions.
J. Planar Chromatogr. 30, 97-105 (2017). Review of current applications of room temperature ionic liquids on planar chromatography as mobile phases. Methylammonium, ethylammonium, propylammonium, isopropylammonium, butylammonium, s-butylammonium, dipropylammonium, tributylammonium were reported to be used as replacements for organic solvents in binary systems. As mobile phase additives, room temperature ionic liquids were used for the separation of peptides and basic drugs in both normal phase and reversed phase chromatography with an emphasis on their role as masking agents. The authors suggested that given the large number of possible cation and anion combinations, systematic methods that characterize solvation properties for both ionic liquids and organic solvents are required.
J. Planar Chromatogr. 14, 371-377 (2001). HPTLC of 18 anions on silica gel plates with 19 different solvents comprising distilled water, pure organic solvents and mixtures of these. Detection by spraying with a saturated solution of silver nitrate in methanol, 0.2-0.5% diphenylamine in 4 mL sulfuric acid, 10% ferric chloride in 2.0 m hydrochloric acid or 0.5% ethanolic pyrogallol solution resp.
Mikrochimica Acta (Wien) II, 47-52 (1984). TLC separation of nitrate from other inorganic ions on silica with ethyl acetate - acetone - methanol 3:1:1 and detection after conversion of nitrate into nitrosyl chloride, and subsequent reaction with beta-hydroxyquinoline and p-amino sulfonic acid (detection limit 5 ng). 55 anions and cations have been shown not to interfere.
J. Planar Chromatogr. 16, 237-243 (2003). Study of the retention behavior of 25 anions on silica gel G-starch 1:1 layers with two-component non-aqueous mobile phases or organic acids and their sodium salts. The RF values of the anions were found to correlate with their lyotropic numbers.
Anal. Letters 18, 1783-1788 (1985). TLC of anions on silica with a) 0.1 M tartaric acid, b) 0.1 M formic acid, c) 0.1M oxalic acid, d) 0.1 M succinic acid. Detection by spraying with 0.1 M fresh silver nitrate.
