Silica gel plates are widely used in thin-layer chromatography (TLC) for separating and analyzing chemical compounds. They serve as a stationary phase, allowing for the separation of mixtures based on polarity and interaction with the silica surface. These plates are essential in laboratories for identifying substances, testing purity, and monitoring reactions in organic synthesis. They are also employed in forensic science to detect drugs, toxins, or other compounds in samples. In the pharmaceutical industry, silica gel plates are used for quality control and drug development. Additionally, they are utilized in biochemistry for analyzing lipids, amino acids, and other biomolecules. Their simplicity, cost-effectiveness, and versatility make them a staple in analytical chemistry.
