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. In organic chemistry, these plates are essential for identifying compounds, monitoring reactions, and assessing purity. They are also utilized in biochemistry for analyzing amino acids, lipids, and other biomolecules. In pharmaceuticals, silica gel plates are employed for quality control, ensuring the consistency and purity of drugs. Additionally, they are used in forensic science to detect and identify substances in samples. Their versatility, ease of use, and cost-effectiveness make them a fundamental tool in various scientific and industrial applications.
