Expanded Van Deemter
The Van Deemter equation can be further expanded to:
Where:
- H is plate height
- λ is particle shape (with regard to the packing)
- dp is particle diameter
- G, ω, and R are constants
- Dm is the diffusion coefficient of the mobile phase
- dc is the capillary diameter
- df is the film thickness
- Ds is the diffusion coefficient of the stationary phase.
Van Deemter's equation indicates that band broadening mechanisms are proportionally dependent on flow rate, inversely proportional to flow rate and independent of flow rate.
