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.
Chinese J. Chromatogr. 7, 181-183 (1989). TLC of 11 amino acids on microcrystalline cellulose with butanol - acetic acid - water 4:1:1. Detection by spraying with 0.5% ninhydrin in acetone. Quantification by densitometry. Comparison with other methods. The results were in good agreement with those obtained with amino acid auto analyzer.
Chromatographia 28, 148-150 (1989). TLC of chlorophyll a and b on cellulose layers with petrol ether - isopropanol 98:2 in the dark. Quantification by densitometry at 410 nm for chlorophyll a and at 452 nm for b. Detection limit 50 ng. The calibration curves were linear in the range of 50-200 ng (r=0.997 for a and 0.995 for b). TLC provides a rapid and simple method for monitoring vegetation damage.
J. Planar Chromatogr. 2, 71-75 (1989). A validation procedure for TLC scanners is presented including determination of signal to noise ratios and instrumental sensitivity. Using test plates, the overall reliability can be determined. Validation of individual parts of the software is done by comparison of different algorithms, for example smoothing algorithms. Validation of spotting devices is shown to be possible by analysis of variances from different types of scans in order to separate errors created by positioning and measurement.
Acta Pharm. Sinica (Yaoxue Xuebao) 24, 397-400 (1989). TLC of bile acids on silica with isooctane - isopropyl ether - acetic acid - butanol - water 10:5:5:3:1. Detection by dipping into a solution of ammonium hydrogen sulfate in ethanol and heating at 110°C for 10 min. Quantification by fluoro densitometry. CV 1.4%. Recovery 98.4%.
J. Planar Chromatogr. 2, 321-322 (1989). TLC of atrazine on silica with toluene - acetone 85:15. Detection by absorbance at 224 nm; detection limit 20 ng/L water.
J. China Pharm. Univ. (Zhongguo Yaoke Daxue Xuebao 20, 184 (1989). TLC of silybin on silica with chloroform - acetone - formic acid 9:2:1. Quantification by fluoro densitometry at 335/>400 nm.
Optimization of mobile phase, detection and direct evaluation. J. Chromatogr. 502, 385-392 (1990). TLC of phospholipids on silica with a mixture of chloroform – methanol – water. Optimization of the mobile phase by using a mobile solvent composition triangle. Improvement of separation of phospholipids by using acetate buffer (pH 4) in the mobile phase instead of water and by impregnation of the silica layer with phosphoric acid. Detection by spraying with Dittmer-Lester reagent. Quantification by densitometry at 720 nm.
Chinese Anal. Chem. (Fenxi Huaxue) 18, 567-570 (1990). TLC of N-phenylphenothiazine and N-(a-pyridyl)-phenothiazine on silica with 1,2-dichloromethane – cyclohexane 1:4 and 1:1. Detection under UV. Identification by IR and NMR after elution. Quantification by densitometry at 260 nm and 246 nm, respectively. Detection limits 2 ng/spot and 5.3 ng/spot, respectively.
