1.16: Methods for Separating Mixtures
Here are a number of common separation techniques: Chromatography. Chromatography is the separation of a mixture by passing it in solution or suspension, or as a vapor (as in gas chromatography), through a medium in which the components move at different rates. Thin-layer chromatography is a special type of chromatography used …
