Programmed multiple development: High performance thin layer chromatography
Journal of the American Oil Chemists' Society, 1977AbstractPoor resolution and sensitivity are not inherent in thin layer chromatography (TLC). They merely re‐flect the fact that TLC, as normally practiced, is not a high performance (efficient) technique. When efforts are made to improve the efficiency of TLC, the re‐sulting improvements in resolution and sensitivity make high performance TLC fully ...

High-Performance Thin-Layer Chromatography: Excellent Automation
2010Product innovations from CAMAG, Switzerland, have made thin-layer chromatography (TLC) a practical laboratory tool for both qualitative and quantitative analysis. Instrumentation was developed to permit more precise auto spotting of the sample. Sample preparation is simplified because precoated clean plates are disposable.

Abstract A simple and precise method using High-Performance liquid [HPLC] and High-Performance Thin-Layer Chromatography [HPTLC] was developed for simultaneous determination of the frequently encountered cucurbitacins B (1), D (2), 3-epi-iso-cucurbitacin D (3), E (4) and I (5) as well as cucurbitacin glycosides E (6) and I (7).

Abstract (HP)TLC is a technique with large applicability in the fields of plant material analysis and stability tests of extracts and finished products. The implementation of a modern standardized methodology led to the increasing of acceptance and recognition of (HP)TLC as competitive analytical method. (HP)TLC has many advantages, such as lower costs,

Analytical Aspects of High Performance Thin Layer Chromatography
2010High performance thin layer chromatographic method is applied for qualitative and quantitative analysis. Qualitative analysis was used for identification of drugs/chemicals, or certain toxic residuals compounds in food or other preparations, and finger printing of herbal drugs/biological matrixes. Quantitative analysis was used for the determination of
