Chromatography
Chromatography is a key laboratory technique used to separate and analyze different components in mixtures, which is essential in pharmaceutical and chemical industries. Think of it like a sorting system that helps scientists identify what ingredients are in a sample, measure their amounts, and ensure product quality. This technique is widely used in drug development, quality control, and research. Common types include HPLC (High Performance Liquid Chromatography) and GC (Gas Chromatography), which are like different methods of sorting, each best suited for specific types of materials.
