J. Liquid Chromatogr. 7, 2711-2718 (1984). Examination of errors contributing to the total variance of automated streaking technique and comparison of these results with computer optimized and zig-zag scanning approaches. The error due to inhomogenous sample distribution is shown to be the most important.

J. Planar Chromatogr. 2, 71-75 (1989). A validation procedure for TLC scanners is presented including determination of signal to noise ratios and instrumental sensitivity. Using test plates, the overall reliability can be determined. Validation of individual parts of the software is done by comparison of different algorithms, for example smoothing algorithms. Validation of spotting devices is shown to be possible by analysis of variances from different types of scans in order to separate errors created by positioning and measurement.

J. Chinese Trad. Patent Med. 30 (12), 1997-1800 (2008). TLC of Hongjinchan granule extracts on silica gel with 1) n-butanol - glacial acetic acid - water 7:1:2; and 2) chloroform - ethyl acetate 7:3. Detection 1) under UV 365 nm; 2) by spraying with 2 % iron(III) chloride in ethanol; 3) by exposure to ammonia vapor for approx. 15 min. Identification by comparison with the standards of the component drugs. Quantification of scutellarin by HPLC.

Lipids 17, 107-110 (1982). TLC of glycolipids (glucocerebromide, lactosyl ceramide, globotriosyl ceramide, gangliotriosyl ceramide, globoside I, asialo-GM1) on silica with chloroform methanol - 0.2 % aq. CaCl2 55:45:10. Detection with anthrone-sulfuric acid reagent.

Chromatographia 28, 445-448 (1989). Description of coupling packed column SFC with TLC. Use of the 2-D system for the presentation of some information about the injected mixture, e.g. polarity, specific spot colors and purity etc. of the eluting peaks with three examples.

J. Chromatogr. 564, 272-277 (1991). TLC on silica with petrol ether - ether (peroxide free) – acetic acid 90:30:1. Detection by spraying with chloroform – methanol 1:1 containing 232 x 10-6 M 2,5-bis-2-(5-tert.-butylbenzoxazolyl)thiophene, and inspecting under UV 365 nm. Quantification by GC.

Teil 2: Die online Kopplung HPLC - AMD. (AMD (Automated Multiple Development); application and online coupling with reversed phase HPLC. Part 2: Online coupling HPLC-AMD). Dünnschicht-Chromatographie InCom Sonderband 1996, 53-71. Online coupling of HPLC and AMD is a two-dimensional separation system, where the completely different separation mechanisms of reversed-phase chromatography in a column and planar chromatography on silica are coupled. Online coupling of HPLC and AMD/HPTLC is capable of separating several thousand substances. With this system practical any number of pesticides in any kind of water sample can be quantified. Without clean-up, interferences of the matrix are reduced to nearly zero. The method is demonstrated by the analysis of a surface water sample spiked with pesticides.

J. Chromatogr. A 819, 35-44, (1998). Presentation of an on-line system consisting of a microbore HPLC syringe pump and a modified TLC autosampler controlled by new software for a personal computer running under MS Windows, which enables to spray the effluent from the HPLC column in fractions onto the plate in a freely definable manner to carry out both complete profiling analysis or typical target compound analysis. Demonstration of typical application to pesticide residue analysis in foodstuffs or environmental samples.
