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. 558, 223-233 (1991). Preparative TLC of nitrogen - containing aromatic compounds on silica with methylene chloride – hexane 3:7. Characterization by GC-MS. Quantification by GC.
Chin. J. Anal. Lab. (Fenxi Shiyanshi) 20 (1), 51-52 (2001). TLC on silica gel with ethyl acetate - methanol 9:1. Detection under UV 254 nm. Quantitation by UV spectrophotometry at 255 nm.
J. Chromatogr. 358, 307-312 (1986). HPTLC of haematoporphyrin IX on octyl-bonded silica with methanol - phosphate buffer (pH 3) 85:15. Examination by densitometry. Purification by multi-step extraction and RP-preparative column chromatography. The purity of the resulting material was checked by HPTLC as well as HPLC and MS.
J. Planar Chromatogr. 9, 435-438 (1996). TLC of several crown ether derivatives of tetraphenylporphyrin (18-crown-6, 15-crown-5, 12-crown-4, 14-crown-4, -p- and -o-isomers ) on silica, alumina, and cellulose with different organic mobile phases in different proportions. Detection via the intense color of the porphyrins, examination under UV 254 or 305 nm.
Acta Chrom. 12, 226-233 (2002). TLC of porphyrins and their complexes with Cu (II) and Ni (II) on silica gel (activated at 120 ºC for 30 min) with carbon tetrachloride – chloroform 1:1 after chamber saturation for 30 min. After drying the plates at RT, spots were visible on the plates. The effects of Cu (II) and Ni (II) cations on the separation of hydroxy and alkyloxy tetraphenylporphyrin derivatives were determined.
Phytochemistry 30, 1405-1408 (1991). TLC of non-acidic indoles on silica with hexane - MEK - 3:7 or benzene - ethyl acetate 9:1. Separation of acidic indoles on cellulose with isopropanol - NH3 - water 10:1:1 or butanol - acetic acid - water 12:3:5. Detection with p-dimethylaminocinnamaldehyde (DMAC) in ethanolic acid.
J. Chromatogr. 519, 171-178 (1990). TLC of 3-hydroxypyridin-4-ones on RP-18 silica with acetic acid - ethyl acetate - hexane - tetrahydrofuran 51:181:101:167, also with same solvent containing 10 mg CPO 94 per 100 mL. Comparison with HPLC. Investigation of the chromatographic behavior in both systems, and discussion of the mechanism. The TLC method is suitable for routine analysis of the compounds in biological matrices.
Anal. Chem. 79, 2101-2108 (2007). TLC of benzodiazepines (midazolam, diazepam, lorazepam, oxazepam, N-desalkyl-flurazepam, triazolam, nitrazepam) on monolithic UTLC phase (prewashed with methanol) with dichloromethane - acetone 93:7 for one-dimensional and toluene - acetone - ethanol - 25 % ammonia 70:20:3:1 for two-dimensional separation in a saturated chamber. Developing distance 2 cm; separation time for 1-D chromatography 2-6 min, for 2-D 4-12 min. Quantitative determination by absorbance measurement at 254 nm; for visual detection the analytes were derivatized by spraying with Dragendorff reagent. Identification of the separated compounds by AP-MALDI-MS. The limits of detection were in the picomole range and thus low enough for bioanalysis.
