Question
What is chromatography?
Advertisements
Solution 1
The process of separating different dissolved constituents of a mixture by their absorption on an appropriate material is called chromatography.
Solution 2
In 1906, Iswett coined the name chromatography (Greek: Chroma, which means colour, and graphy, which means writing) to describe the process of separating coloured compounds from plants. Since the technique is now commonly utilised for the separation, purification, and characterisation of the components of a mixture, whether they are coloured or colourless, the word has lost its original meaning. It is based on the fundamental idea of dividing an organic compound mixture's constituent parts between two phases. One phase is known as the stationary phase and can be either a liquid or a solid supported on a solid. The other phase, referred to as the moving phase, is characterised by motion and can be made up of either a liquid or a gas.
