Sorbents for thin-layer chromatography in pharmaceutical analysis

Abstract

Compounds contained in medicinal plant raw material and DL-tryptophan have been separated by thin-layer chromatography using various sorbents including cellulose, RP-modified silica gel, chiral precoated plates, and plates with a concentrating zone.

Polymerized high internal phase emulsion monolithic material: a novel stationary phase of thin layer chromatography

“…[1][2][3] It is important to select a suitable stationary phase when using TLC to separate mixtures. Thin chromatographic layers can be formed from different organic and inorganic sorbents 4,5 and different plates are commercially available. The most commonly used conventional TLC plates consist of sorbent layers formed from irregular ca.…”
