Chromatography paper sheets, often simply referred to as chromatography paper, are a type of specialized paper used in chromatography experiments. Chromatography is a laboratory technique used for separating and analyzing mixtures of substances into their individual components based on their differential interactions with a stationary phase and a mobile phase. Chromatography paper serves as the stationary phase in certain types of chromatography. Chromatography paper is an essential tool in analytical chemistry and is widely used in research, quality control, and educational settings to separate and analyze complex mixtures. It allows scientists to investigate the composition of substances and is a valuable technique in fields such as chemistry, biochemistry, and biology.
