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

CBS 113, 5-7 (2014). HPTLC/AMD as a screening method to identify previously unconsidered_x000D_
substances. HPTLC of water samples on silica gel LiChrospher in the AMD 2 with a 25-step gradient, starting in the isocratic mode with 5 steps acetonitrile – dichloromethane 1:1 for focusing, followed by 15 steps from acetonitrile – dichloromethane 1:1 to dichloromethane and then 5 steps from dichloromethane – n-hexane 4:1 to n-hexane. Final migration distance 80 mm. Detection under UV 254 nm, UV 366 nm and white light. Densitometric evaluation by absorbance measurement at 190, 200, 220, 240, 260, 280, and 300 nm. Target zones were eluted with the TLC-MS Interface offline with water – acetonitrile 1:1 and deuterium oxide – acetonitrile 1:1, respectively, each with an addition of 5 mmol/L ammonium acetate, at a flow rate of 0.2 mL/min using the oval elution head (4 x 2 mm) for analysis with a QTOF/MS. With the molecular formula information, different databases were searched and H/D exchange (replacing protons in the molecule by deuterium which leads to a mass shift in the ESI MS spectra) was used to reduce the quantity of possible structures.
J. Planar Chromatogr. 31, 243-249 (2018). HPTLC of diazinon (1) and chlorpyrifos (2) in the leave extracts of lavender and rosemary on silica gel with petroleum ether – ethanol – glacial acetic acid 95:5:1 for (1) and 90:10:1 for (2). Quantitative determination by absorbance measurement at 254 nm. The hRf values for (1) and (2) were 54 and 50, respectively. Linearity was in the range of 10-1600 ng/zone for (1) and 40-2000 ng/zone for (2). The intermediate precision was below 2 % (n=3). The LOD and LOQ were 3 and 10 ng/zone for (1) and 12 and 40 ng/zone for (2), respectively. Average recovery was 100.8 % for (1) and 99.9 % for (2).
J. High Resol. Chromatogr. 10, 465-466 (1987). TLC of 8 organophosphorus pesticides on silica with petrol ether - benzene - ethyl acetate - 60:30:10 and petrol ether - benzene - chloroform - ethyl acetate 60:30:5:5. Detection by spraying with 0.01 % 2-methyl-thioacridone in dichloromethane and heating for 15 min at 200 °C, examining under UV 366 and 254 nm. Identification by Rf.
J. Planar Chromatogr. 2, 387-389 (1989). TLC separation of carboxylic acid herbicides on calcium sulfate layers (NP-TLC and S-TLC) with acetone, benzene, carbon tetrachloride or chloroform and on impregnated (olive oil, paraffin oil, silicone oil) calcium sulfate layers (IP-RP-TLC) with benzene and carbon tetrachloride, carbon tetrachloride and benzene, chloroform and benzene, and ethyl acetate and carbon tetrachloride as eluents.
Chinese J. Chem. Anal. (Lihuajianyan, Huaxuefence) 25, 126 (1989). TLC of 7 sulfur-containing organophosphorus pesticides and DDVP on silica with benzene – methanol 9:1. Detection by spraying with 0.2% palladium chloride.
J. Planar Chromatogr. 6, 413-415 (1993). TLC of nitroaromates and carbazoles (9-nitroanthracene, 1-nitronaphthalene, 2-nitrofluorene, 1-nitropyrene, carbazole, 1,2,7,8-dibenzcarbazole, 1,3-dinitropyrene, 2,7-dinitrofluorene) on silica with hexane - dichloromethane 1:1. Detection under UV 254 and 365 nm, followed by spraying with freshly prepared reducing agent (0.1 g sodium borohydride) dissolved in a mixture of 15 mL methanol, 3 mL water, and 1 mL of 0.05% copper(II)chloride solution and again observation under UV at 365 nm. Azaarenes were separated on cellulose with DMF - water 1:4. Detection by observation under UV both before and after reaction in a chamber containing trifluoroacetic acid fumes.
