No diffusion, no pores and no void quantity make transport among mobile and stationary period really fast
These HPLC programs have two pumps with two independent solvent paths, two dosing models inside the autosampler, and two detectors, but hold the footprint of only one HPLC method.
The amount of retardation mostly will depend on the nature from the analyte and also the composition of both equally stationary and cellular phases.

The two parts of the cellular phase are usually termed "A" and "B"; A will be the "weak" solvent which lets the solute to elute only little by little, though B would be the "strong" solvent which speedily elutes the solutes from the column.
