Why are solvents used in chromatography?
Solvents are used to help separate components of a mixture. The solute selected should have the ability to dissolve the components of the mixture.
Here is a video of an experiment conducted to separate the components of water soluble ink. Note the pigments present in the ink are all water soluble.

Solvents are used in chromatography to dissolve the sample components and allow them to travel through the stationary phase, separating them based on their affinity for the stationary and mobile phases.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
