Apr 01, 2016 The stationary phase consists of a packed column in which the packing or solid support itself acts as stationary phase, or is coated with the liquid stationary phase (high boiling polymer). Most analytical gas chromatographs use capillary columns, where the stationary phase coats the walls of a small-diameter tube directly (i.e., 0.25 m film ...

What is the Difference Between Mobile Phase and Stationary

What Is The Difference Between Mobile Phase And Stationary

Oct 13, 2019 The main difference between the mobile phase and stationary phase is that the mobile phase is the solvent moving through the column, whereas the stationary phase is the substance, which stays fixed inside the column. Furthermore, the mobile phase can be either liquid or gas while the stationary phase is a solid or liquid supported on a solid. Moreover, components of the mixture with
