Silica gel plates are widely used in thin-layer chromatography (TLC) for separating and analyzing chemical compounds. They serve as the stationary phase, allowing researchers to identify and quantify substances in mixtures based on their mobility. These plates are essential in pharmaceutical labs for drug purity testing, in forensic science for analyzing unknown substances, and in biochemistry for studying complex biological samples. Additionally, they are employed in environmental testing to detect pollutants and in food safety to identify contaminants. Silica gel plates are valued for their efficiency, reproducibility, and ease of use in analytical workflows.
