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. 580, 125-134 (1992). Discussion of the analysis of 31 drugs and drug metabolites in human hair by TLC, HPLC, GC, and GC-MS.
CBS 101, 12-13 (2008). During a drug substance stability study a mass imbalance was discovered in light degraded samples. HPTLC on silica gel first with ethyl acetate - heptane, then, after drying, with tetrahydrofuran in a horizontal developing chamber. Detection under UV 254 nm and by densitometry at 240 nm. During another project differences in color between batches of a drug substance were observed. HPTLC on amino phase with methanol in a horizontal developing chamber. Detection under white light and under UV 366/>400 nm.
Chinese J. Pharm. (Zhongguo Yaoxue Zazhi) 28, 550-552 (1993). TLC on silica with hexane - chloroform - methanol 5:3:1. Quantification by densitometry at 254, 249 and 214 nm for diazepam, methaqualone and estazolam, respectively.
J. Liq. Chromatogr. Relat. Technol. 30, 2369-2383 (2007). TLC of 2-arylpropionic acids, namely ibuprofen and naproxen, on silica gel and silica gel impregnated with a 0.03 mol/L solution of L-arginine in methanol by dipping for 2 s, with ethanol and ethanol containing several drops of acetic acid. Quantitative determination by absorbance measurement at 254 nm. It was demonstrated that the crystalline chirality of the silica gel adsorbent is most probably responsible for the horizontal enantioseparation, whereas the molecular chirality of L-arginine deposited on the silica gel layer is responsible for the vertical enantioseparation.
J. Chromatogr. B. 699, 408-412 (1995). HPTLC on silica with three solvent systems. Detection by means of UV light and color as well as the Rf values in different systems. Detection limit 0.1-0.4 µg for 5 benzodiazepines.
Asian J. Chem. 18(4), 2669-2672 (2006). TLC of lamivudine and zidovudine on silica gel with toluene - methanol - n-hexane 14:3:2. Quantitative determination by absorbance measurement at 275 nm. Linearity for lamivudine and zidovudine was in the range of 0.8-2.0 and 1.5-4.0 µg/zone, respectively. The average recovery was 99.4 - 100.3 % for both drugs. The method can be applied for routine simultaneous estimation in combined dosage form.
J. Chromatogr. B 690, 315-319 (1997). HPTLC on silica with hexane - ethyl acetate - anhydrous acetic acid 75:25:2. Quantification by densitometry at 222 nm. Detection limit 50 ng. Precision < 3.2%, recovery 85%.
J. Planar Chromatogr. 22, 201-206 (2009). TLC of ambroxol hydrochloride and doxycycline hyclate on silica gel with ethyl acetate - ethanol - glacial acetic acid - water 90:40:5:10 with chamber saturation for 1 h. Detection under UV 254 nm. Quantitative determination by absorbance measurement at 254 nm for ambroxol hydrochloride and 270 nm for doxycycline hyclate.
