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.
Proc. 6th Int. Symp. Instrum. Planar Chromatogr., (Interlaken 1991), Inst. Chromatogr., Bad Dürkheim, FRG, 103-112 (1991). Separation technique for block copolymers (BC) of homopolystyrene (PS) and homo-poly-tert-butylmethacrylate (PTBMA) on different silica gels. Detection by spraying with 3.3% KMnO4-solution in conc. H2SO4 followed by heating. Eluents were MEK, mixtures of cyclohexane - toluene - MEK as well as cyclohexane - toluene - MEK - pyridine in various amounts.
J. Chromatogr. 562, 99-110 (1991). Separation and identification of non-volatile and thermally unstable mixtures by TLC on silica and reverse-phase TLC on octyl-bonded silica with different solvent systems. Identification by MS including both direct and scanning TLC-liquid ion MS. The methods are simple, useful and easy to perform, and can overcome the problems associated with indirect and direct coupling of LC/MC. Scanning TLC-LS/MS can be carried out like GC/MS and gives good quality of chromatograms and mass spectra.
J. Planar Chromatogr. 3, 236-242 (1990). HPTLC separation of anabolic steroids on silica; androgens and gestagens with cyclohexane - ethyl acetate - ethanol 24:16:1 in the first direction and chloroform - acetone 9:1 in the second direction; estrogens with chloroform - benzene - ethanol 36:4:1 in the first direction and hexane - ether - dichloromethane 4:3:2 in the second. An additional confirmation of the identity of the steroids is possible by HPTLC on silica RP-18 with methanol - water - toluene 13:4:1 in the first direction and hexane - dichloromethane - acetonitrile 8:2:1 in the second. Detection by fluorescence after immersion in a 5% sulfuric acid - ethanol solution for 30 sec and viewing under UV 366 nm. Method for routine HPTLC analysis.
J. Planar Chromatogr. 3, 356-358 (1990). OPLC of alkaloids (lupinine, sparteine, lupanine, 13-hydroxylupanine, and dihydrofuro(2,3-b)quinolinium salts) on alumina with ethyl acetate (quinolizidine alkaloids) an on silica with ethyl acetate - formic acid - water 10:1:1. Visualization of quinolizidine alkaloids by spraying with Dragendorff’s reagent and by fluorodensitometry at 310/>420 nm.
J. Planar Chromatogr. 3, 537-538 (1990). TLC of samples of hot rubber-bitumen products rubberised bitumen emulsions of silica with heptane - toluene 1:9, followed by visual evaluation
Don. grown in Egypt. Herba Hungarica 30, 98-104 (1991). TLC of rhamnose, xylose, arabinose, mannose, glucose, galactose, glucuronic acid and galacturonic acid on silica impregnated with 0.1M sodium sulfate developed with ethyl acetate – acetic acid – methanol – water 12:3:3:2. Visualization by spraying with thymol – sulfuric acid reagent.
Acta Chimica 128, 819-822 (1991). TLC of bulgaramine on silica with dichloromethane – ethanol 10:1. Visualization under UV or by exposing to iodine vapor.
J. Planar Chromatogr. 5, 35-40 (1992). HPTLC of lasalocid sodium, monensin sodium, narasin sodium, salinomycin sodium on silica and RP-18 with ethyl acetate – water 100:3 resp. with methanol – 5% aqueous acetic acid 9:1 (2 x). Lipids (i.a. L-a-phospatidylcholine-ß-linoleoyl-y-palmitoyl, dipalmitoyl L-a-phosphatidylethanolamine, triolein, oleic acid, L-a-dipalmitoyl phosphatidylcholine) were chromatographed with cyclohexane – ether – acetic acid 90:10:1 on silica, with chloroform on RP-18. VPF resposes on silica and RP-18 have been compared for both classes of compounds: the respose of the polycyclic ether antibiothics narasin and salinomycin on RP-18 plates was three times greater than on silica; lipids with the exception of cholesterol could be detected only on silica plates. Quantification by fluoro densitometry at 366/>400 nm.
