Mobile Phase

The mobile phase is the fluid phase that carries the analyte through the chromatographic column during separation.

The statement of the theorem

Let v(t)\mathbf{v}(t) be the velocity vector of the mobile phase flow through the column. The mobile phase is characterized by its flow rate FF (volume/time) and its composition CM={CM,j}j=1N\mathbf{C}_{M} = \{C_{M, j}\}_{j=1}^{N}. The transport of an analyte ii is governed by the mass balance equation:\n∂Ci∂t+∇⋅(vCi)=DM∇2Ci\frac{\partial C_i}{\partial t} + \nabla \cdot (\mathbf{v} C_i) = D_M \nabla^2 C_i \nwhere DMD_M is the hydrodynamic dispersion coefficient.
