Question

what is the principle of chromatography?

Answer 1

Principle: The samples are subjected to flow by mobile liquid onto or through the stable stationary phase. The sample components are separated into fractions based on their relative affinity towards the two phases during their travel.

The fraction with greater affinity to stationary layer travels slower and shorter distance while that with less affinity travels faster and longer.

Answer 2

Principle is that:-

Heavier objects settle down whereas lighter objects remains at top when spun rapidly.
