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:

J. Chromatogr. Sci. 33, 417-425 (1995). Quantitative hydrocarbon group type analysis of a deasphalted heavy oil from petroleum and its derived hydrocracking products by configuration of detector, an automatic sample spotter, a careful selection of the operating parameters. Use of the method for the detection and quantification of saturates, alkylaromatics, aromatics, polar and an uneluted fraction. Discussion of the repeatability and the linearity range for each separated fraction.
J. of Chromatogr. A 1281, 135-141 (2013). The use of detergents for the extraction, solubilization and purification of membrane proteins (MPs) is necessary due to their hydrophobic nature. Detergent quantification is essential to routine analysis because the concentration of amphiphiles is crucial in the crystallization process. HPTLC of detergents (in small quantities, bound to solubilized MPs) on silica gel with dichloromethane – methanol – acetic acid 80:19:1. The optimum HPTLC conditions were investigated using n-dodecyl-beta-D-maltoside (DDM), the most popular detergent for membrane protein crystallization. Quantification by fluorescence measurement at 366 nm using a Hg lamp. The calibration curve was linear in the range of 100-1600 ng of DDM in water and the limit of detection of was 50 ng/zone, which is the best LOD achieved to date for a routine detergent assay (not modified by the addition of NaCl, commonly used in protein buffers). In comparison with other techniques (colorimetry, GC, and FTIR) the HPTLC method has the advantage of no prior sample treatment for concentration or extraction, and no chemical labeling is required. In comparison with TLC, the HPTLC method is 100 times more sensitive. The HPTLC method is suitable for routine analysis, assay results are obtained within 3 hours and only few microliters of sample are needed.
Anal. Biochem. 164, 307-314 (1987). TLC on silica with chloroform - methanol - water 78:21:1.
J. Chromatogr. Sci. 31, 220-224 (1993). TLC of various non-ionic tensides consisting of ethylene oxide oligomer mixtures on silica and alumina with 55 systems. Calculation of the solvent strength and selectivity for each chromatographic system and correlation of them with the physicochemical parameters of the solvent using stepwise regression analysis.
Chromatographia 70 (7-8), 1277-1282 (2009). HPTLC of preservatives on three stationary phases of different polarity: RP-18, RP-18W and cyano phase, with methanol – water mixtures in different volume proportions. The resulting RM values showed a linear decrease with increasing methanol concentration of the mobile phase (determination coefficients for all stationary phases were >0.98). The retention behavior of the preservatives on RP phase is in good agreement with their polarity. Principal component analysis showed that for all three stationary phases the same lipophilic interactions take place.
J. Chromatogr. 437, 59-82 (1988). TLC of 54 amines on silica with benzene and benzene - ethyl acetate - acetone 100:5:1. Detection by spraying with N-chloro-2,6-dichloro-P-benzoquinone monoimine in buffered alkaline medium. Identification of several imprecisely defined products. Establishment of theoretical correlations between chemical structures, Rf values and colors of spots.
J. Planar Chromatogr. 10, 463-464 (1997). TLC on silica with hexane (12 cm), and, after drying - in the same direction - with petrol ether (10 cm). Detection by spraying with 20% ethanolic phosphomolybdic acid and heating at 105°C. Quantification by densitometry at 600 nm.
J. Planar Chromatogr. 22, 19-23 (2009). HPTLC of 26 UV filter substances and their photodegradation products on LiChrospher silica gel (prewashed with methanol) by automated multiple development with mixtures of tert-butyl ether - n-hexane. Detection under UV light at 254 and 366 nm. Bioassay by immersion of plates for 1 s in a suspension of Vibrio fischeri bacteria followed by evaluation in dark.
