WebWe use a solvent, called the mobile phase, to dissolve a sample of a soluble mixture. The solvent carries the mixture up a solid called the stationary phase. Some components of the mixture are carried up the solid by the solvent more quickly than others. We say that components that travel faster have a greater affinity to the mobile phase.
