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

J. Planar Chromatogr. 31, 383-388 (2018). HPTLC of cocaine hydrochloride (1) and levamisole hydrochloride (2) on silica gel with cyclohexane – toluene – diphenylamine 75:15:10. Quantitative determination by absorbance measurement at 230 nm. The hRF values for (1) and (2) were 24 and 48, respectively. Linearity was between 200 and 2400 ng/zone for (1) and 100 and 1200 ng/zone for (2). LOD and LOQ were 14 and 42 ng/zone for (1) and 6 and 19 ng/zone for (2), respectively. The intermediate precision was <2 % (n=6). Average recovery was 99.8 % for (1) and 99.9 % for (2).
J. Planar Chromatogr. 31, 265-271 (2018). HPTLC of aspirin (1), paracetamol (2), and caffeine (3) in saliva, after ultrasound-assisted emulsification microextraction, with chloroform on silica gel with ethyl acetate - acetic acid 19:1. Detection under UV light at 254 nm. Quantitative determination using ImageJ software. The hRF values for (1) to (3) were 90, 80 and 50, respectively. Linearity ranged between 4 and 200 μg/zone for (1) to (3). LOD and LOQ were 12 and 38 μg/zone for (1), 8 and 26 μg/zone for (2), and 7 and 23 μg/zone for (3), respectively. The intermediate precision was <10 % (n=3). Recovery was in the range of 89-94 % in saliva for (1) to (3).
Proc. Intern. Symposium on TLC with special Emphasis on OPLC, Szeged, 67, (1984). OPLC (OPTLC) of amino acids on silica with 1) butanol - acetic acid - water 4:1:1, 2) phenol -1 % SDS - isobutanol - propanol - butanol - acetic acid 70:28:2:2:2:1.7. Detection with ninhydrin + Cu or Cd acetate reagent. Detection with videodensitometer, coefficient of variation 6 %.
VII. Comparison of analytical methods for determination of impurities in tetracycline pharmaceutical preparations. J. Chromatogr. 314, 303-311 (1984). HPTLC of various tetracyclines on silica with acetone - 5 % aq. sol. of Na2 EDTA 10:1 and RP-TLC on C18-plates with methanol - acetonitrile - 0.5 M oxalic acid (aq. pH 2.0) 1:1:4 or 1:1:2. Detection by UV 366 nm or with 0.5 % Fast Violet B aq. solution and pyridine. Quantification by scanning at the dual-wavelength mode at 366/600 nm for 4-epitetracycline and chlortetracycline and at 425/650 nm for anhydrotetracycline and 4-epianhydrotetracycline. RP-TLC-densitometry appears to be a precise method for the determination of tetracyclines.
