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. The saved items can be printed to PDF using the print function of your web browser.
J. Planar Chromatogr. 20, 283-285 (2007). TLC of benzalkonium bromide homologs (with C2, C4, C6 to C16, C18 C20) on silica gel in twin-trough chambers with isopropanol - water - acetic acid 114 or methanol - chloroform - acetic acid 50101. Detection with iodine vapor or by derivatization with Dragendorff’s reagent.
Photosensitized degradation of a homogeneous nonionic surfactant hexaethoxylated 2,6,8-trimethyl-4-nonanol. J. Agric. Food Chem. 34, 547-551 (1986). TLC of 2,6,8-trimethyl-4-nonanol and de-ethoxylated photoproducts, i. a. polyethylene glycol EO 2,3,4,5 and 6, on silica with water saturated methyl ketone (1. dimension) and benzene - acetone - water (2. dimension). Detection by UV and autoradiography
J. Planar Chromatogr. 5, 87-91 (1992). Comparison of ANS (8-anilo-1-naphthalene sulfonate, ammonium salt), rhodamine B, nile red, dichlorofluorescein with hematoporphyrin; visual comparison under UV 366 nm. Limits of (visual) detection (LOD) were 10-20 ng for the cationic surfactants, and 5 and 10 ng, respectively, for the phospholipids (sphingomyelin and lecithin) and cholesterol.
J. Planar Chromatogr. 18, 160-163 (2005). TLC of rare earths (La(III), Ce(III), Pr(III), Sm(III), Gd(III), Er(III)) on silica gel and silica gel impregnated with 2.5 M ammonium nitrate with different mixed mobile phases containing di(2-ethylhexyl)dithiophosphoric acid as a complexing agent. The best results were obtained by use of ethyl methyl ketone - tetrahydrofuran - 1 M di(2-ethylhexyl)dithiophosphoric acid 1781. Double development was used to obtain better separation of consecutive rare earths.
J. Planar Chromatogr. 20, 347-351 (2007). TLC of DTAB on soil, silica gel, alumina, and kieselguhr with fifteen mobile phases, such as aqueous solutions of ammonium sulfate and urea, with chamber saturation for 10 min. Detection by spraying with modified Dragendorff reagent. Among the systems studied the best system for selective separation of DTAB from multicomponent mixtures of other surfactants was kieselguhr - 0.1 M ammonium sulfate. Semi-quantitative determination by spot-area measurement.
) (Chinese).Chinese J. Chromatogr. 5, 191-193 (1957) (Sepu). TLC of nonionic surfactants with different hydrophobic groups and polyethylene glycols of different molecular weight on silanized silica with methanol - water 82 and 73. Detection by iodine vapor. Quantification by densitometry.
J. Planar Chromatogr. 6, 70-73 (1993). TLC of non-ionic surfactants (e.g. nonylphenyl ethylene oxide oligomers) according to the length of the ethylene oxide chain on aluminum oxide with chloroform - acetonitrile mixtures. The optimum separation of pairs of surfactant oligomers with the longest ethylene oxide chains required eluents of the highest strength (highest acetonitrile concentration).
Acta Chrom. 17, 272-291 (2006). TLC on silica gel with 0.1 M glutamic acid – methanol – acetone 111 has been found to be highly suitable for separation and identification of cationic and non-ionic surfactants. Visualization by use of Draggendorf reagent or iodine vapour. Spectro-photometric determination of tetradecyltrimethylammonium bromide at 670 nm after the spot extraction. The method has been used for identification of tetradecyltrimethylammonium bromide and Triton TX-100 in saline water, river water, and domestic waste water. The effects of sample pH, polarity of the alcohol and nature of the amino acid in the mobile phase, and the presence of alumina, kieselguhr, or cellulose in the silica gel layer have been examined.
