Abstract Normal-phase and reversed-phase thin-layer chromatographic systems for the separation and analysis of [ 3 H]metabolites of 20-hydroxyecdysone have been developed. These include separations involving multiple development (in one or more solvent systems), two dimensional techniques, reversed-phase and ion-pair chromatography.

High-Performance Thin Layer Chromatography Instrumentation
2023HPTLC is one type of planar chromatography and the most advanced form of instrumental TLC. HPTLC equipment involves an autosampler for the application of a specific amount of sample on the plate, after spotting of sample the plate is developed in a TLC development chamber after development the plate is dried and visualized using visualizer.

Anticircular high performance thin‐layer chromatography
Journal of High Resolution Chromatography, 1978AbstractThe principal analytical details for the third of three possible modes in high performance thin‐layer chromatography are given, namely the anticircular mode. Separation is achieved by allowing the mobile phase to enter the plate layer on a precise outer circle line, from where it flows towards the centre with nearly constant speed.

Stationary phases for high-performance thin-layer chromatography
Journal of Chromatography A, 1980Abstract The characteristics of commercially available high-performance thin-layer chromatographic quality thin-layer plates pre-coated with silica gel, cellulose, chemically bonded phases or polyamide are discussed and compared with those of pre-coated layers used in conventional thin-layer chromatography.

Quantitation in high-performance micro-thin-layer chromatography
Journal of Chromatography A, 1975Abstract Silica gel 60 F254 pre-coated plates for nanogram-scale thin-layer chromatography were developed for high-performance thin-layer chromatography (HPTLC) on the basis of silica gel of pore size 60 A. Under the usual chromatographic conditions, it was possible to achieve a plate height of 12 μm.
