Separation of Components from a Mixture of Red and Blue Inks by Paper ChromatographyBy Robolab Technologies In Atal Tinkering Labs ATL, More Info
Chromatography is one of the most important separation techniques extensively used to separate mixtures into their components. It was first employed by a Russian scientist Mikhail Tsvet. In the paper chromatographic technique, the mixture of substances is applied onto a Whatman filter paper strip called stationary phase. A pure solvent or a mixture of solvents is allowed to move slowly over the stationary phase. This moving phase is called mobile phase. When mobile phase is moved over the mixture on the stationary phase, the components of the mixture gets gradually separated from one another.
This video explains how to separate the components from a mixture of red and blue inks by paper chromatography.
