Silica gel plates are widely used in thin-layer chromatography (TLC) for the separation and analysis of chemical compounds. They serve as the stationary phase, allowing for the separation of mixtures based on their polarity and interaction with the silica surface. These plates are essential in laboratories for identifying substances, monitoring chemical reactions, and determining the purity of compounds. They are particularly valuable in organic chemistry, pharmaceuticals, and biochemistry for analyzing drugs, amino acids, lipids, and other organic molecules. Additionally, silica gel plates are utilized in forensic science to detect and identify trace substances in evidence samples. Their ease of use, cost-effectiveness, and ability to provide quick results make them a staple in analytical chemistry workflows.
