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

J. Liq. Chrom. & Rel. Technol. 25, 3151-3165 (2002). TLC of the colors of tomato, orange and marigold (i.a. lycopene, b-cryptoxanthin, lutein) on RP-18 with acetonitrile - acetone - n-hexane 11:7:2 and acetone - water 9:1. The visible absorption spectra of the colors were measured by densitometry at 370-700 nm without isolation of the colors.
J. Chromatogr. 547, 403-409 (1991). Optimization of the analytical parameters in OPTLC separation of dyes and bergamot oil on Empore sheets. Discussion of the performance and comparison with pre-impregnated HPTLC.
(Chinese). Chinese J. Chromatogr. (Sepu) 17, 503-505 (1999). TLC of dyes on various clothes on silica with five solvent systems. Optimization of the solvent systems by correlation analysis of the Rf data. 26 dyes extracted from the same colored wool fiber and acrylic fiber samples were identified by comparison of the Rf value and the spot color.
CBS 103, 13-15 (2009). HPTLC of azo dyes (Sudan I, II, III, IV, B, Sudan orange G, Sudan red 7B, Para red) in spice samples on caffeine impregnated silica gel with isohexane - methyl ethyl ketone 5:1 with chamber saturation for 10 min. Densitometric absorption measurement at 390, 415, 500, 525 and 550 nm. The limits of detection were approx. 10 mg/kg. Confirmation of suspected compounds in samples by comparison of UV spectra. TLC-MS analysis in positive ESI mode further confirms positive findings.
J. Planar Chromatogr. 29, 45-58 (2016). Vertical chamber dielectrochromatography (V-LDEC) of two lipophilic dyes, Sudan blue (1) and Sudan II (2) on plates containing increasing amounts (1, 2, 3, 4, 6, 8, 10) g of barium titanate in 35 g alumina with toluene – n-hexane 1:1. The periods of maintaining the electric field consisted of 3 cycles, one cycle of about 17 min. The voltage between the armatures for each experiment was maintained at 3 kV AC value. Improved separations were obtained for the ratios of 2:35 and 3:35 (g/g) barium titanate – alumina both in equicurrent and mostly in countercurrent.
J. AOAC Int. 101, 1397-1401 (2018). HPTLC of sudan red dyes, namely Sudan orange G (1), Sudan red G (2), Sudan I (3), Sudan II (4), Sudan III (5) and Sudan IV (6) in spices and spice mixtures on RP-18 acetonitrile – methanol – aqueous ammonia solution (25 %) 40:9:1. Quantitative determination using a flatbed scanner with a 16-bit resolution. The hRF values for (1) to (6) were 54, 48, 57, 35, 26 and 17, respectively. Linearity was between 20 and 500 ng/zone for (1) to (6). LOD and LOQ were 17 and 35 ng/zone for (1), 11 and 21 ng/zone for (2), 14 and 31 ng/zone for (3), 12 and 24 ng/zone for (4), 18 and 42 ng/zone for (5) and 16 and 37 ng/zone for (6), respectively.
A simple chromatographic system for the identification of inks. J. Chromatogr. 475, 451-456 (1989). Proposal of a simple TLC system for the identification of inks based on cellulose layer, solution of ammonium sulfate or 1% sodium chloride as developing solvent; UV detection and photo dokumentation.
Chinese J. Environ. Chem. (Huanjing Huaxue) 12, 225-230 (1993). TLC of 7 dyes on silica with 14 different solvent systems (two for each dye). Identification by comparison colors and Rf values with those of standards. Confirmation and quantification by HPLC.
