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 efficient separation of mixtures based on polarity and molecular interactions. In laboratories, these plates are essential for identifying substances, monitoring reaction progress, and purifying compounds. They are also employed in quality control processes in pharmaceuticals, food, and cosmetics industries to ensure product consistency. Additionally, silica gel plates are used in forensic science for analyzing trace evidence and in environmental testing to detect pollutants. Their versatility and ease of use make them a fundamental tool in analytical chemistry.
