Principle
High Performance Thin Layer Chromatography is capable of separating organic compounds. Principle of HPTLC have similar approach and employ the same physical principles of TLC (adsorption chromatography) i.e. the principleof separation is adsorption. The mobile phase solvent flows through because of capillary action. The components move according to their affinities towards the adsorbent. The component with more affinity towards the stationary phase travels slower. The component with lesser affinity towards the stationary phase travels faster. Thus, the components are separated on a chromatographic plate.
Application
HPTLC is a powerful tool for rapidly comparing several samples in parallel, checking for adulteration, monitoring purity and stability, and quantifying marker compounds. Because of its many benefits the technique is used in various application fields. The analyte includes herbal drug, food, forensic, biotechnology, cosmetics, pharmaceutical, chemical, environmental samples.
Method
The user needsto have knowledge of layers and solvents to be used for separation. In the absence of this knowledge, a method development step is necessary.
