Contemporary Thin-Layer Chromatography in Pharmaceutical Quality Control

Abstract

The progress in layers, instrumentation, and the development of automated scanning densitometers have led to a remarkable improvement of the features of thin-layer chromatography (TLC) and especially its high performance version (HPTLC). Contemporary TLC or HPTLC combines the techniques' inherent advantages which include high sample throughput, simultaneous processing of standards and samples, flexibility, easy postchromatographic visualization techniques, and the ability to handle complex or crude samples with minimum sample cleanup - with improved selectivity, sensitivity, and accuracy. It is a very economical chromatographic technique that competes with and complements HPLC. Development and validation of procedures can be performed rapidly in full accordance with all current international guidelines.
