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. 32, 61-64 (2019). HPTLC of monocrotophos in biological samples (pieces of stomach, small and large intestine, liver, spleen, kidney, and lungs) on silica gel with hexane - acetone 19:1. Detection by spraying with a chromogenic reagent (2 g chloranil mixed with 2 g sodium nitrite dissolved in 10 % nitric acid solution). The hRF value of monocrotophos was 76.
J. Planar Chromatogr. 32, 59-60 (2019). TLC of p-phenylenediamine on silica gel with ethyl acetate - diethyl ether 1:1. Detection by spraying with aqueous alkaline solution of Folin’s reagent (0.5 % Folin’s reagent in 5 % sodium carbonate solution). The hRF value of p-phenylenediamine was 45. The LOD for p-phenylenediamine was approximately 3 μg by visual evaluation.
J. Planar Chromatogr. 32, 65-68 (2019). HPTLC of endosulfan in biological samples (pieces of stomach, intestine, liver, spleen, kidney, and lungs) on silica gel with hexane - acetone 4:1. Detection by spraying with a 10 % sodium hydroxide solution and then with diphenylamine reagent (2 g diphenylamine in 20 mL glacial acetic acid and 20 mL ethyl acetate), following by exposure to sunlight for 10 min. The hRF values of the endosulfan coordination complex (alpha and beta isomers) were 66 and 85. Zones were stable for 8 to 10 days.
J. Planar Chromatogr. 32(1), 51-53 (2019). TLC of amitraz in visceral tissues (stomach, intestine, liver, spleen, and kidney) on silica gel with hexane - acetone 4:1. Detection by spraying with 10 % sodium hydroxide solution, followed by heating at 80 °C for 10 min. The plate was then removed, kept to attain room temperature and sprayed with 5 % chloranil solution. The hRF values were between 49 and 51. The zones were stable for 8 h.
J. Planar Chromatogr. 20, 69-71 (2007). TLC of mycotoxins (aflatoxin B1, B2, G1, ochratoxin A, sterigmatocystin, chaetomins, roquefortine C, penicillic acid, trichothecenes) on silica gel, prewashed with methanol, with chloroform - xylene - acetone 6:3:1. Detection under UV and by spraying with 0.5 % anisaldehyde in sulfuric acid followed by heating at 110 °C for 10 min.
J. Planar Chromatogr. 22, 59-63 (2009). HPTLC of paraquat, diquat, difenzoquat, mepiquat, and chloromequat on LiChrospher silica gel with 1-propanol - methanol - 2.5 M aqueous sodium chloride 1:1:3. Detection by immersion for 2 s in a solution of 50 mg sodium tetraphenyl borate in 50 mL of water containing 50 µL concentrated hydrochloric acid. The wet plate was illuminated for 5 min with UV light at 254 nm which resulted in the formation of fluorescing spots corresponding to mepiquat, chloromequat, and difenzoquat. Immediately after illuminating at 254 nm all spots were illuminated for 10 min with UV light at 365 nm, which converted all compounds into fluorescent derivatives. Then the dry plate was dipped into ethylene glycol - methanol 1:1 for 2 s, which enhanced the fluorescence by a factor of two. Detection by fluorescence measurement and averaged densitograms were obtained in the emission wavelength range from 440 to 480 nm.
J. AOAC Int. 93, 556-561 (2010). TLC of methamphetamine (MA), 3,4-methylenedioxymethamphetamine (MDMA), and 3,4-methylenedioxy-N-ethylamphetamine (MDEA) on silica gel with hexane - chloroform 1:9 and HPTLC on cyano phase with benzene - diethyl ether - petroleum ether (40-60 °) - acetonitrile - ethyl methyl ketone 4:7:7:1:1 with chamber saturation for 30 min. The hRf value of MA, MDMA, and MDAE on silica gel were 28, 23, and 36, repectively, and on cyano phase 35, 30, and 40, respectively. LOD on silica gel were 0.8, 0.6, and 1.2 µg/mL (in plasma) for MA, MDMA, and MDEA respectively.
A new approach in forensic analysis. J. Planar Chromatogr. 24, 108-112 (2011). HPTLC of ditalimfos, edifenfos, and tolclofos-methyl on silica gel, prewashed with methanol, with n-hexane - acetone 9:1 in a twin-trough chamber with saturation. Quantitative determination by densitometry in absorbance mode at 254 nm, the wavelength of maximum absorption for all three fungicides. The hRf values of all three organophosphorus fungicides increased with increasing contents of acetone in the mobile phase.
