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. You can export your saved items to PDF by clicking the download icon.
Chromatographia 35, 627-630 (1993). TLC separation of free fatty acids into two fractions, a more mobile group of saturated and monounsaturated fatty acids and a less mobile group containing polyunsaturated fatty acids, on silica with hexane - acetic acid - water 50:2:1. Detection by exposure to iodine vapor, and under UV 254 nm. Determination of polyunsaturated fatty acids by HPLC.
J. Chromatogr. A 803, 235-239 (1998). Modeling of ion-pair HPLC separations by using continuous OPLC. Study of the distribution of several cationic ion-pairing reagents on the layer with mobile phases containing different quaternary ammonium salts, which volumes varied between 4.5 to 67.5 cm3 equivalent to a 1 to 15 bed volume of the given layer. Measurement of the concentration of the reagents after chromatography in 10 samples of the stationary phase used.
Chromatographia 52 (3/4), 175-178 (2000). Investigation of methods for the separation of test mixtures of 10 flavonoids using isocratic RP-HPLC, gradient RP-HPLC, and a coupled isocratic RP-HPLC-NP-TLC system. TLC of the flavonoid fractions separated on RP column, by using 3-step gradient elution with methanol - ethyl acetate, giving a complete separation of the investigated compounds.
J. Chinese Trad. Patent Med. (Zhongchengyao) 25 (10), 798-801 (2004). TLC on silica gel with 1) ethyl acetate - butanone - formic acid - water 10:7:1:1; 2) benzene - acetone 10:1; 3) petroleum ether - ethyl formate - glacial acetic acid 18:1:1. Detection 1) under UV 365 nm, 2) by spraying with 5 % solution of vanillin - acetic acid - perchloric acid and heating at 105 ºC, 3) by spraying with 10 % H2SO4 in ethanol and heating at 105 ºC. Identification by fingerprint techniques. Quantitation of icariine by HPLC.
J. Chromatogr. Sci. 54 (4), 639-646 (2016). Presentation of a low-cost method for digital image analysis of the separation results of colorless analytes on TLC plates. Quantitative TLC-digital image analysis was performed using a universal staining reagent (iodine vapor), an office scanner and a commonly available software (Microsoft Paint) for analysis of red, green and blue colors (RGB values). Urinary creatinine is used as a model analyte to represent a sample in complicated biological matrices. TLC on silica gel with butanol – ammonia solution – water 4:1:5 up to 6 cm. Detection by exposure to iodine vapors for 30–60 min. The Green value offered the best results in the linear working range of 0.08 - 0.93 mg/mL. The precision (%RSD) was 2.0 % (n=10), and the LOD 0.24 µg per zone. Comparison of the urinary creatinine concentrations determined by TLC-digital image analysis using the green value calibration graph with results obtained by HPLC showed that both are well consistent.
J. Chromatogr. 437, 221-229 (1988). TLC on silica with methanol. Detection under UV. Elution with methanol. Further separation by HPLC.
Biomed. Chromatogr. 4, 165-167 (1990). TLC of pyrimethamine metabolites on silica with methanol - acetic acid - NH3 50:12:0.1. Determination by HPLC after elution.
J. Planar Chromatogr. 7, 197-201 (1994). Regulatory agencies usually require that more than one chromatographic method is used during drug development. This paper describes a method of graphically displaying and correlating reverse phase HPLC retention times with TLC Rx values. Exploitation of the orthogonal nature of the different chromatographic selectivities shown.
