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. Planar Chromatogr. 6, 34-37 (1993). Use of chitin and derivatives prepared by treatment of chitin with transition metals for the separation of optical isomers of amino acids: good separation on chitin-Cu with binary or ternary mixtures of organic solvents. The dependence of hRf values on the composition of the mobile phases has been demonstrated.
J. Chromatogr. 668, 481-484 (1994). Separation of the two pairs of monomethyl and dimethyl derivatives from the methylation of 5-ethyl-5-phenyl-2-thiobarbituric acid by TLC on silica with 1) chloroform, 2) chloroform - toluene - acetone 2:2:1, 3) chloroform - toluene - acetone 2:2:1, 3) cyclohexane - ethyl acetate 4:1. Detection under UV 254 nm. Also HPLC.
J. Planar Chromatogr. 10, 108-113 (1997). RP-TLC of 18 racemates (i.e. flavanone derivatives, pyrethroids) on MCTA (with silica as binder) with ethanol - water 4:1, 2-propanol - water 4:1, 3:2, 1:1, 2:3, methanol - water 4:1 in a thermostated chamber, saturated for 1 h at 25°C. Detection under UV 254 and 366 nm. Quantification by densitometry at 260 nm (absorbance).
J. Planar Chromatogr. 13, 33-36 (2000). Direct racemic resolution of dansyl-DL-amino acids on silica gel plates impregnated with vancomycin (0.34 mM) as chiral selector. The mobile phase enabling successful resolution of most of the racemic dansyl amino acids were acetonitrile - 0.5 M aqu. NaCl 5:2 and 14:3. Detection with a fixed dual-wavelength UV light at 254 nm. Detection limit 2.1µg. New sorbent for separation of chiral compounds resulting in a simple, rapid, sensitive, cost-effective method.
J. Planar Chromatogr. 15, 220-222 (2002). TLC of the enantiomers of thiochroman-4-ol, benzoin, a-methylbenzoin and anisoin on plates prepared from mixtures of tribenzoylcellulose and silica gel G with water - ethanol, water - 2-propanol and n-hexane - 2-propanol. Densitometry at 295 nm. The enantiomers of a-methylbenzoin and anisoin could not be separated.
Biomed. Chromatogr. 22 (11), 1237-1242 (2008). TLC of dl-penicillamine on silica gel 1) impregnated with L-tartaric acid; 2) impregnated with (R)-mandelic acid; and 3) with no impregnation but with chiral modifier added to the mobile phase. The mobile phases used were 1) acetonitrile - methanol - water 5:1:1; 3) ethyl acetate - methanol - water 3:1:1; and 2) acetonitrile - methanol - 0.5 % aqueous L-tartaric acid (pH 5) - glacial acetic acid 70:10:11:7. Detection by exposure to iodine vapors. The limit of detection of both was 120 ng/zone by use of L-tartaric acid (either by impregnation or added to mobile phase), and 110 ng/zone by use of (R)-mandelic acid. (R)-mandelic acid was found to be successful as a chiral impregnating reagent.
J. Planar Chromatogr. 27, 319-320 (2014). TLC of DL-amino acids and their L- or D-forms on home made silica gel plates impregnated with recrystallized vancomycin with n-butanol - methanol - water 25:6:5 after chamber saturation for 15 min. Detection by spraying with ninhydrin solution (0.2 % in ethanol). The vancomycin allowed for enantiomeric resolution of D- and L-amino acids.
Bio Ind. 4, 327-338 (1987). A review with 75 references on host-guest chromatography and the use of cyclodextrins as stationary phase in TLC and LC with examples of separations of carboxylic acid, amino acid enantiomers and xylidine isomers.
