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. 14, 360-363 (2001). HPTLC of 7 amines (p-chloroaniline, o-toluidine, o-anisidine, 2-naphthylamine, 4-chloro-o-toluidine, 2-diaminotoluene, 2-aminio-4-nitrotoluene) on silica gel plates with dichloromethane (developing distance 4.5 cm), drying and development with toluene - tetrahydrofuran 10:1 to a distance of 8.5 cm. Visualization under UV 254 nm. New quantitative very simple, accurate, low-cost, rapid and highly selective method.
Anal. Bioanal. Chem. 387, 1083-1093 (2007). A new HPTLC method for trace analysis (low µg/kg range) of the five heterocyclic aromatic amines PhIP (2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine), MeIQx (2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline), 4,8-DiMeIQx (2-amino-3,4,8-trimethylimidazo[4,5-f]quinoxaline), norharmane (9H-pyrido[3,4-b]indole) and harmane (1-methyl-9H-pyrido[3,4-b]indole) in meat samples has been established. HPTLC on LiChrospher silica gel WRF with methanol – chloroform 1:9. Using the ADC2, the plate activity was adjusted to 34 % relative air humidity with MgCl2 x 6H2O for 15 min and, at the same time, chamber saturation with 35 mL aqueous ammonia 28 % – ultrapure water 1:4 was performed for 20 min, followed by alkaline plate preconditioning for 15 min. The development was performed in a fresh chamber. Quantitative determination by absorbance measurement at UV 262 nm and 316 nm, and fluorescence measurement at UV 366/>400 nm. The UV wavelength 316 nm was later substituted by 313/>340 nm for a more selective and sensitive determination of PhIP in the meat matrix. Mass spectrometric analysis was performed in ESI+ mode for confirmation of positive findings. The method was validated according to ICH guidelines. Repeatability was better than 3.3 % (n=14), the intermediate precision (n=6, peak area) was 0.4 % (PhIP), 0.6 % (MeIQx), 0.7 % (4,8-DiMeIQx), 0.9 % (norharmane) and 1.1 % (harmane). Reproducibility of the migration distance was better than 1.3 % (n=6). LODs were 4 ng/band for PhIP, 5 ng/band for MeIQx, 4 ng/band for 4,8-DiMeIQx, and 0.4 ng/band each for norharmane and harmane. LOQs were 6 ng/band for PhIP, 14 ng/band for MeIQx, 11 ng/band for 4,8-DiMeIQx, and 0.8 ng/band each for norharmane and harmane. Selectivity in the meat matrix was proven. Confirmation of the substances found in meat was performed by MS. In the working range RSDs of the calibration functions were between 1.9 and 3.6 %.
