5.what is meant by stationary phase and mobile phase in chromatography
Answers
Answer:
The process of separating different dissolved constituents of a mixture by their absorption on an appropriate material is called chromatography
It is named so, because earlier it was used to separate mixtures containing coloured components only but these days this technique is applied to colourless substances too.
The simplest form of chromatography is paper chromatography.
Chromatography is based on the principle where molecules in mixture applied onto the surface or into the solid, and fluid stationary phase (stable phase) is separating from each other while moving with the aid of a mobile phase. ... Based on this approach three components form the basis of the chromatography technique.
Stationary phase:
The solid or liquid phase of a chromatography system on which the material to be separated is selectively adsorbed.
Mobile phase:
In a chromatography system the liquid or gas that flows, moving the materials to be separated at different rates over the stationary phase.
