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.
Chem.(BUNSEKI KAGAKU) 34, 346-350 (1985). (Japanese) (Improvement of scanning photoacoustic densitometer for thin-layer chromatography and determination of squalene in human skin surface lipid). Photoacoustic densitometer with a lock-in amplifier with a reference frequency of 80 Hz and a band pass filter of 3 Hz. Detection limits (S/N = 2) of squalene and Sudan Red 7B were 50 ng and 35 ng, resp. Relative SD, 3.7 % for squalene (860 ng) and 3.3 % for Sudan Red 7B (194 ng). Method applied on content of squalene in the human skin surface lipid.
(Japanese). Proc. Hoshi Coll. Pharm. 28, 51-57 (1986) (Hoshi Yakka Daigaku Kiyo). Description of a light scanning photoacoustic densitometer for determination of organic compounds separated on TLC plate with application examples. Discussion of the use of light emitting diode and laser diode as the light source.
Anal. Letters 22, 507-518 (1989). Demonstration of a voltammetric detector coupled with thin-layer chromatography for the quantification of trace organic compounds on the plate. Detection limits for p-anisidine and p-phenetidine, about 10 ng. Linearity, 2 orders of magnitude.
J. Pharm. Biomed. Anal. 8, 253-257 (1990). A densitometric method for determination of complex mixtures of conjugated oestrogens in raw material and tablets was developed. The proposed procedure comprised hydrolysis of sodium sulfate esters of oestrogens and oestradiol, equilenin, 17a-dihydroequilenin, the chloroform extraction of free oestrogens and methyltestosterone (internal standard). TLC on silica with chloroform - cyclohexane - dioxane - triethylamine 45:40:10:6. Quantification by densitometry at 254 and 280 nm. Detection limit 0.06 µg, recoveries 97,1% (conjugated oestrogens) and 103,2% (tablets). The proposed method is simple, rapid, and reproducible.
Amer. Lab. 25, 24 I-M (1993). Description of video densitometer with a few examples, involving electronic record-keeping, micro focus lens, and system versatility.
Chinese J. Chromatogr. (Sepu) 15, 310-313 (1997). Discussion of the coherent features and the important analytical performance parameters such as accuracy, precision, reproducibility, specificity, detection and quantification limits, linearity and range, etc. in TLC, stressing on the validation methods and the acceptance criteria for sample preparation, sample stability in solution and on plate, sample exposure time, robustness and quality of the stationary and mobile phases, sample application, chamber saturation, detection as well as quantification. It is recommended that the definition of the validation parameters and the validation procedures for quantitative TLC should be given whenever results are reported.
Proc. Intern. Symp. on Planar Separations, Planar Chromatography 2001, pp. 149-153. Essential values in optical resolution of cameras and digital photo systems, computer memory and processor speed, data transmission speed and costs of mass memory have been reached in the last years and are now available which are the prerequisite for PLC digital video quantitation.
Acta Chrom. 17, 250-260 (2006). The ChromImage flatbed scanner densitometer with Galaxie-TLC software has been used for the quantification of silica gel HPTLC. The visible mode was evaluated by determination of the recovery of rhodamine B from a four-dye mixture and by determination of the precision of replicate analysis. Determination of caffeine in analgesic tablets and a cola beverage were performed in the fluorescence-quenching mode.
