Chromatography is relied on by many disciplines as a method of separating the components of a mixture. The basic idea of the process is that distinct compounds have different levels of solubility, ...
Chromatography is a key technique in chemistry used to separate and study the components of a mixture. It works by moving different substances at different speeds through a medium, allowing scientists to identify and measure the amounts of each component. This method is important in many fields, including chemistry, biology, and environmental science. Chromatography also helps scientists ...

Chromatography separates mixtures into their parts — here’s how it works, the main types, and where it’s used in labs, food safety, and medicine.
Chromatography is a process for separating components of a mixture. To get the process started, the mixture is dissolved in a substance called the mobile phase, which carries it through a second substance called the stationary phase. The different components of the mixture travel through the stationary phase at different speeds, causing them to separate from one another. The nature of the ...
