Question

what is chromatography state its principle write any two advantages of chromatography

Answer 1

Chromatography is an analytical technique where in a sample mixture under test is separated into different components.”This is both a qualitative and quantitative method. The sample gets separated under the influence of a mobile phase (moving phase) over a stationary phase.These separated components are later identified and also quantified.
Chromatography principle:
Chromatography is based on the principle of separation of compounds into different bands (color graphs) and then identification of those bands.The preferential separation is done due to differential affinities of compounds towards stationary and mobile phase. After separation of the compounds, they are identified by suitable detection methods.he differences in affinities arise due to relative adsorption or partition coefficient in between components towards the both phases.

Answer 2

Chromatography is a laboratory technique for the separation of a mixture. The mixture is dissolved in a fluid called the mobile phase, which carries it through a structure holding another material called the stationary phase.

The principle is:The samples are subjected to flow by mobile liquid onto or through the stable stationary phase.
